Part II of Brian Sommer’s Deep Dive into Wedges
By Brian Sommer, PhD
Of all wedge specifications, bounce might be the most discussed – and the least usefully understood. The elementary definition is simple enough. Bounce describes the relationship between the leading edge and the sole’s lowest contact point in a specified orientation. More bounce generally helps the leading-edge resist digging. Less bounce can allow the leading edge to sit closer to the surface. And then the simplicity ends. Because two wedges stamped with the same bounce number may not behave remotely the same.
Sole width matters. Camber matters. Heel relief matters. Toe relief matters. Trailing-edge relief matters. A wider sole can behave as though it has considerably more bounce than the engraved number might suggest. A heavily relieved sole can allow the face to be opened without presenting nearly as much resistance to the turf.
Then there is the minor complication of the golfer. Open the face and the geometry changes. Move the handle and the geometry changes. Add forward shaft lean. Reduce it. Change the lie angle presented at impact. Enter the ground more steeply. Enter it more shallowly. Suddenly the number engraved onto the wedge is no longer a full description of what the grass experiences. The original draft makes this distinction explicitly: nominal bounce is not the same thing as the effective interaction created by sole width, relief, orientation and delivery.
This explains something I have noticed repeatedly while trying different wedges. I often notice less difference between various bounce and grind combinations than the fitting literature tells me I ought to notice. That does not make the designs meaningless. It may mean something more interesting. The golfer adapts. Give a reasonably accomplished wedge player several slightly different clubs and he may begin altering delivery, face angle, speed, entry point or handle position without consciously deciding to do so. The club changes. The golfer changes with it. That raises a fitting question that I find considerably more interesting than “What bounce should you play?”
When two wedges produce similar outcomes, are we observing evidence that the wedges are essentially interchangeable for that player under those conditions? Or are we observing the golfer successfully adapting to two different tools? Perhaps both. Either way, the golfer belongs in the explanation. And that is where many fitting narratives become oddly one-sided. Every additional specification becomes another candidate for optimization. A golfer who has played perfectly competent wedge shots for twenty years can suddenly be informed that his grind is inappropriate for his delivery, his bounce unsuitable for his turf, or the loft spacing in his set numerically offensive.
Perhaps it is. But before we remedy the defect, it seems reasonable to ask whether there is one. Does he dig excessively? Does the club bounce into the ball? Can he open the face? Does he struggle from bunkers? Can he control launch? Is there a shot he repeatedly cannot produce? Or does his equipment merely fail to conform to the preferred matrix? These are not the same thing. A mismatch on a specification sheet is not necessarily a problem in a golfer’s experience. And if there is no problem in the golfer’s experience, one ought to be slightly suspicious of somebody arriving with a solution.
Bermuda Has a Vote
There is one place where I personally notice bounce and sole design much more distinctly: very short shots played into the grain on Bermuda grass. Anyone who plays enough Bermuda knows the shot. The ball is sitting innocently enough. There appears to be almost nothing between the clubface and the ball. Yet the grain is running toward you, and the turf can grab the leading edge with the enthusiasm of a parking brake. Here, sole design becomes considerably less theoretical. I generally prefer bounce anyway, but into sticky Bermuda grain I particularly want the club to resist burying itself. I do not want a knife. I want a sole. And even there, simply asking whether a wedge has “high bounce” is inadequate.
A comparatively broad sole with useful camber may resist digging more effectively than a narrow sole with the same nominal bounce number. Heel or trailing-edge relief may make the club much easier to use with an open face. A flatter, broader sole may provide greater resistance against penetration. But again, the golfer participates. Someone presenting considerable forward shaft lean may remove much of the bounce available to him. Another player using a more neutral handle position may expose considerably more of the sole. Neither is inherently correct in the abstract. The shot decides what is useful. This is why the Bermuda example matters beyond Bermuda.
It exposes the weakness of simple rules. A low-bounce wedge may be wonderful from a tight, firm lie with the grain. Turn around, move fifteen yards, find a sticky patch into the grain and the identical club may feel considerably less cooperative. Does that mean you need another wedge? Maybe. It may also mean you need to discover another way of using the wedge you already own. These are not competing religions. A golfer may discover through experience that a different sole genuinely makes a particular shot easier. Excellent. Another may alter the way the sole approaches the grass and discover that the club already in his bag is much more versatile than he imagined.
Also, excellent. The important thing is that the golfer encounters the problem directly. This is central to how I think about golf more generally. The golfer does not need to begin with a theory of the correct solution. He can experience what happens. Hit the shot. Notice the interaction. Alter something. Notice again. The ground is remarkably forthcoming with information if we allow it to speak before the fitting chart does. Instead of beginning with, “How much bounce should I play?” perhaps a better question is: “What shots do I actually have to hit?” A golfer dealing regularly with damp Bermuda, grain and soft bunkers faces a different environment from someone playing firm links turf. The golf club does not know whether it is in Florida or Scotland. It knows the surface it just struck.
The Seasons Do Not Know Your Bounce Number
This leads naturally to another piece of categorical wedge advice: high bounce for soft conditions, low bounce for firm conditions and, therefore, perhaps a different wedge setup when the seasons change. Perhaps. But calendars do not strike golf balls. Conditions do. If summer means lush, saturated turf and winter means thin, hard ground, then a different sole may genuinely prove useful.
If bunkers become much firmer and shallower, the golfer may prefer something that lets the leading-edge work closer to the sand. Tour players sometimes make exactly those adjustments. They
have every conceivable equipment option available and can change configurations when tournament conditions warrant it. But the operative phrase is when conditions warrant it.
The better principle is this: Change because the conditions have created a problem, not because the calendar says you should have one.
There is practical value in familiarity. A golfer who has hit hundreds or thousands of shots with one wedge has developed an understanding of how that club behaves. The understanding may not be verbal. It may not be numerical. It may not be particularly conscious. In fact, I would argue that much of the useful understanding probably is not. He has encountered wet lies, dry lies, heavy rough, grain, tight turf, fluffy turf, soft sand and firm sand. He has opened the face. Hooded it. Hit the ball low and high. Landed it short and long. He knows the club. Not as a collection of specifications. As an experience. That knowledge should not be dismissed simply because it is difficult to put onto a launch-monitor screen.
Changing wedges may produce an advantage under certain conditions. It also introduces something unfamiliar. The trade-off cannot be resolved by reading the bounce number. For most golfers, a sufficiently versatile wedge setup probably covers far more conditions than they are sometimes encouraged to believe. A player who has learned to vary face angle, speed, trajectory and delivery may have little reason to own separate summer and winter collections. There will be exceptions. A professional moving from soft parkland turf to extraordinarily firm championship conditions may have excellent reasons to change. But a Tour professional’s access to unlimited equipment is not evidence that the recreational golfer requires the same inventory. Golf equipment should solve problems. It need not anticipate problems that have not appeared. Otherwise, we are no longer solving problems. We are manufacturing them.
Do We Really Need Four Wedges?
The modern answer to wedge gapping has also become remarkably standardized. Four to six degrees between wedges is a common recommendation. Vokey, for example, has recommended approximately 4–6 degrees, often associated with roughly 10–15 yards of separation for many players.
Fine.
It is a sensible guideline. The trouble begins when a guideline begins behaving like legislation. Pitching wedge. Gap wedge. Sand wedge. Lob wedge. Four clubs. Four lofts. Four stock yardages. A satisfying spreadsheet. I have never found the arrangement particularly attractive for my own golf. I carry a 56 and 60 in addition to my pitching wedge. I have never felt much need for a gap wedge. For me, another wedge does not necessarily provide another solution. Sometimes it merely provides another choice. And more choices are not synonymous with more freedom.
I would rather know how to hit different shots. A full pitching wedge. A three-quarter pitching wedge. A lower one. A softer one. More speed. Less speed. A different trajectory. A 56 hit several different distances. A wedge chart tends to treat each yardage as though it requires its own answer. But the yardage does not need a club. It needs a shot.
To be fair, modern iron design has complicated this. Pitching wedges have become stronger, sometimes reaching 43 degrees or less. Once a pitching wedge begins approaching what earlier generations would have regarded as a 9-iron loft, an additional wedge may make obvious practical sense. If somebody has 43 degrees at one end and 56 at the other and cannot reliably produce the distances in between, another club may be extremely useful. But notice what has happened. We have identified an actual problem. Now the equipment solves it. That is very different from beginning with the assumption that everybody must possess the same number of wedges because convention says there ought to be four.
My own pitching wedge is around 46 degrees, followed by a 56. Ten degrees would horrify some gapping charts. Yet it does not particularly horrify me. I can alter the pitching wedge. I can alter the 56. What matters is not the number engraved on the sole but the shots available to me. That distinction runs directly into one of golf’s more curious modern habits: treating variability as a weakness rather than a capacity. A golfer who can hit a pitching wedge 130 yards, 110 yards, 95 yards and 80 yards has not necessarily compromised his precision. He may have developed a repertoire. Another golfer may prefer four or five wedges and standardized yardages. Nothing is wrong with that either. These are different ways of playing golf. The useful question is whether the arrangement serves the golfer. Not whether it satisfies the spreadsheet.
If a golfer repeatedly encounters a distance he cannot cover reliably, put another wedge in the bag. If he already covers it comfortably with clubs he knows, then the missing loft is not evidence of an incomplete golf set. Four degrees is a fitting convention. It is not a Rule of Golf. And this is where the discussion of wedges touches something considerably larger. Skill is not merely the ability to repeat one standardized motion with a series of specialized tools. Skill can also be the ability to vary. To perceive. To adapt. To discover what the club will do. There is a tendency in modern golf to believe that reducing variation produces expertise. Sometimes it does. Sometimes expertise consists precisely in becoming more capable of variation.
The Wedge Does Not Play the Shot
This, finally, is where I think the modern wedge becomes a useful illustration of a larger confusion in golf. We have become extraordinarily good at describing things. Launch. Spin. Dynamic loft. Attack angle. Bounce. Effective bounce. Grind. Friction. Sole interaction. Center of gravity. Carry distance. Dispersion. None of these measurements are inherently objectionable. Many are genuinely useful. But describing something more precisely is not the same thing as causing better performance.
The map remains a map. The golfer still has to encounter the territory. This is why I resist the implication that improvement must proceed through an increasingly elaborate architecture of fitting systems, prescribed motions, yardage matrices and explanatory models. Sometimes they help. Sometimes they do not. Sometimes the additional description clarifies what a golfer is experiencing. Sometimes it merely stands between the golfer and the experience. The useful question is not whether a system, technology or fitting method can produce information. Of course it can. The useful question is whether that information increases the golfer’s contact with what is actually happening. Does he notice the sole entering the turf? Can he sense the face? Can he create the trajectory? Can he adapt to the lie? Can he strike one shot differently from the previous one because the shot requires something different? Can he remain available to what the situation is asking of
him? That, to me, is much closer to skill.
And it explains why my own wedge philosophy is relatively uncomplicated. I generally like more bounce. I like forged wedges. I carry fewer wedges than some fitting systems would recommend. I have preferences in shape and feel. But I do not regard those preferences as commandments. If another wedge allows me to hit a shot I cannot reliably produce now, I am interested. If different conditions reveal an actual weakness in the equipment I am using, I am interested. If another grind makes a difficult shot noticeably easier, I am interested.
That is equipment solving a problem. But I am considerably less interested in being told that a problem exists because a number on the sole, a gap in a chart or a position in a fitting matrix says it ought to. Change what increases contact with reality. Leave the rest alone. The modern wedge is a marvelous golf club precisely because it can do so many things. Its sophistication should enlarge the golfer’s freedom; not become another set of instructions he must obey.
And perhaps that is the irony. After nearly a century of development, manufacturers have created wedges capable of extraordinary versatility. Different soles. Different grinds. Different face orientations. Different turf interactions. Different trajectories. Different speeds. Different shots. The equipment has become progressively more capable of variation. One might hope the golfer would be granted the same privilege. The wedge is a tool. Not a syllabus. Not a diagnosis. Not an identity. And certainly not proof that the golfer requires another intervention.
Gene Sarazen’s original insight remains wonderfully instructive. There was a problem. He changed the club. The shot became easier. Almost a century later, surrounded by launch monitors, grind matrices, fitting algorithms and proprietary terminology, we might occasionally benefit from retaining something of that simplicity.
Find the shot. Find the problem. Use the tool. And play.
