First in a series:
1) I just obtained a used set of XYZ irons that I really like. Can you custom fit them to me?
The quick answer is that any existing club can be optimized. That still doesn’t mean it would be the best choice for a given individual. One issue here is there are 20+ variables I can change as a clubmaker to optimize a club. Most golfers, however, only include a few of these in their definition of custom fitting such as lie angle. A more important issue that is overlooked is whether or not the clubs involved are actually well-suited for the golfer to begin with and, therefore, worth modifying. Let’s start with the XYZ clubs first:
To Modify or Not to Modify?
Using an extreme example, it makes no sense to re-grip Grandpa’s Wilson Staff Blades for a beginning golfer just because they’re free. That’s because the head design and shaft characteristics are the most important factors when matching clubs to swings. A high handicapper, which includes not only beginners, but average golfers that shoot around 100, would play much more efficiently with a more forgiving head design and enjoy the game more. Said another way, although a tennis shoe may fit your foot properly, that doesn’t mean it’s ideal for basketball.
How about the 5-year old XYZ irons you just got on eBay? The head design is relatively current and they come from one of the major OEM companies so they’ve got to be good, right? The first thing to remember is that most clubs end up on eBay because they didn’t work well or the owner found something better. The second thing to understand is that with virtually no standards in the industry for major factors like loft and shaft flex, the odds are very good that the measured specs for the clubs will not match the head or shaft labels. The bottom line is if you have to make any major changes like reshafting, the used clubs could end up costing more than a new custom fit set.
What’s Not to Like?
Unlike Facebook, it’s not so straight-forward to define the term “like” as it pertains to a golf club. In my world of clubfitting, repeatable ball performance determines whether or not I like a golf club. It may have an appealing shape, but it has to work for me. This view, however, often clashes with that of many golfers who make emotional buying decisions based on name brand, tour results, or the way a club looks without ever trying the club. This is especially important for clubs that can’t be returned because aesthetics will never trump results. So, before you commit to purchasing used clubs make sure you are doing so for the right reasons. If you’ve always wanted a certain brand and model, go for it. Just make sure to allow for some added expenses to get these clubs to match you and your swing properly.
Basic Fit vs. Optimized
Getting back to club modifications, the sky is the limit on the types of changes that can be made. Basic fitting issues such as re-gripping and lie/loft bending are common for previously-owned sets and are used to get clubs to match your physical body characteristics such as hand size. Optimizing clubs to match your swing, however, is an entirely different process involving launch monitors and head/shaft fitting systems. By focusing on the science of clubmaking, an optimal combination of head, shaft, and grip can be identified for any individual’s needs. This includes determining whether a more suitable head and/or shaft would improve upon the performance of an existing club.
What’s a Golfer to Do?
Here’s the approach I recommend to my clients regarding club modifications:
1) If you’re convinced your clubs are fine the way they are, but could use a few minor tweaks to get them to fit better, focus on making sure the shaft lengths are a reasonable fit, the grips are doing their job, and leave it at that. You can always throw in lie/loft adjustments and swingweight changes, but they are of minor importance compared to having the right head and shaft.
2) If you’re set on optimizing existing clubheads, start by comparing your existing clubs to a test club that has been selected by a qualified fitter as part of a fitting session. If your clubs hold their own, consider having a clubmaker temporarily convert an appropriate club from your set to a test head that can be used with a wide variety of test shafts. The measured results from this level of testing will replace educated guesses regarding the optimal shaft and flex to use. Just be aware there may still be a better mousetrap out there with regards to head design.
3) If your goal is to eliminate as many variables as possible, perform the same tests as above, but add an appropriate selection of head designs to the process. Choose the head/shaft combination that consistently optimizes ball performance for your swing. Following this process will leave no stone unturned and put you and your swing in charge of your game, which is good unless you’re looking for reasons to blame your clubs.
