TSH GOLF - FAQs
Every one of the key fitting specifications in any set of irons, that’s what – the lofts, lies, shaft flex, shaft bend profile, shaft weight, total weight, headweight feel (swingweight or MOI), grip style and grip size. Not only that, but it is possible that some golfers could be more comfortable with a slightly different single length than other golfers. In short, even though the lengths of each iron will be the same, what that length should be as well as each one of the other key fitting specifications should be custom fit and custom built for each golfer. Single length does NOT mean “one size fits all” in the manner of the way big golf companies sell their clubs in standard form, off the rack. Single length sets still need to be properly custom fit to each golfer based on their size, strength, athletic ability and swing characteristics for the best single length and lie along with the right shaft weight, shaft flex, shaft bend profile, swingweight/MOI, set makeup and grip size/style.
Here’s a little fact of life the golf industry never talks about when the subject of customclubfitting comes up.There are no established standards within the golf equipment industry forshaft flex.The R flex from one company may have the same stiffness as the S flex from another company,or the A flex from yet another company.The result is a lot of golfers walk away from their clubbuying experience without the right fit for the shafts in their new clubs.Accurate shaft fitting has to consist of four important steps:Measure the driver and middle-iron (#5, 6, or 7-iron) swing speeds of the golfer.The golfer’sswing speed measurements must then be compared not to letter codes for flexes, but to atechnically accurate list of swing speed ratings of many different shafts.Fit the weight of the shaft to the physical strength and aggressiveness of the golfer’s downswingmove at the ball.Physically strong golfer + aggressive downswing transition + fast downswingtempo = heaver shaft weight (>85g woods, >115g irons).Less strong golfer + more passivedownswing transition force and smooth tempo = very light shaft weight (<65g woods, <65-75girons).In between these extremes for the golfer strength and downswing tempo = mediumshaft weight (70-80g woods, 75-85g irons).Adjust the swing speed rating of the shaft to be chosen for the golfer to the intensity of thegolfer’s downswing transition move.Very aggressive transition move to start the downswing =choose a shaft with a swing speed rating slightly higher than the golfer’s actual swing speedmeasurement.Very smooth and easy transition to the downswing = a shaft with a swing speedrating slightly lower than the golfer’s swing speed. Average transition force and tempo = choosea shaft with a swing speed rating in which the golfer’s actual swing speed is in the middle of therange.
Choose the shaft’s Bend Profile Design (distribution of stiffness over the length of the shaft) tomatch the golfer’s unhinging of the wrist-cock angle on the downswing, also called therelease.The bend profile of a shaft is how its stiffness can be distributed over the length of theshaft.For golfers with a late release, shafts with a tip firm bend profile (the tip end is thesmaller end of the shaft) are a better fit.Golfers who release the wrist cock angle early in thedownswing need shafts with more flexibility in the tip design.In between with a midway releasemeans a tip medium bend profile.One last point to guide your shaft fitting; the higher the clubhead speed, the later the wrist cockrelease and more aggressive the downswing, the more the shaft becomes a vital component ofperformance in the club.The slower the swing speed, the earlier the release and less aggressivethe swing tempo, the weight of the shaft becomes far more important for the golfer than thestiffness design of the shaft for contributing to shot performance.The only way for all golfers tofind the best shaft for their swing is through professional custom clubfitting
Enabled by the new 2-piece hollow body design, the Center of Gravity moves progressively through the set from lowest and most rear located on the #5 iron to highest and most forward located on the GW and SW to achieve more consistent shot shape and shot height for each iron in the set The hollow body design throughout the set increases the MOI of each head by removing all mass from the inside of the head to be distributed all around the CG.The hollow body construction also enables the CG progression and uniform impact sound between the high COR and conventional COR heads in the set Low number irons are better matched with their loft to CG position to achieve preferred shot shape/height and allow a wider range of players to be able to effectively hit the #5 and 6 irons to fly and carry with proper distance gaps Traditional GW and SW profile shapes are combined with milled faces and a custom sole grind make the wedges a great choice even if they were standalone wedges and not part of the single length design 275g head weight with hoselweight bore allows assembly to any single length between 35.5” and 37.5” while still being able to achieve a reasonable range of swingweight/MOI (depending on shaft weight and grip weight)
That’s a very interesting point in Single Length set fitting. Think about it this way, using the following example. Let’s say you have two golfers and after a fitting analysis for a conventional set of irons, it is determined that Golfer A needs his lengths to be +1” over standard, while Golfer B is best fit into a standard length set. That means the 5 iron in Golfer A’s set would be 39” while the 5 iron in Golfer B’s set would be 38”. But let’s say that both Golfers become aware of the Single Length concept and express an interest to be fit into such a set. And let’s also say that the Single Length set both see is offered in a “standard” single length of 37”. Does Golfer A need his Single Length set to be 38” since he was advised to use a +1” over standard length in his conventional set of irons? Probably not, and here’s why. In Golfer A’s conventional set of irons, 37” is the length of his +1” over length #9 iron. While in Golfer B’s conventional iron set, 37” is the length of his standard length #7 iron. Thus it could be said that the 37” single length would be a proper fit for either golfer, even though in a conventional set Golfer A measured to need +1” longer than standard. Interesting, eh? In the end, there may be an occasional situation in which a golfer who needs a longer length in a conventional iron set may need the length of a Single Length set to be a bit longer than the length range the set was designed to follow. However, we do urge clubmakers to try to keep all golfers within this range between 36.5 and 37 inches for purposes of more successfully fitting the golfer to a suitable total weight + headweight feel in the clubs. But in the end if the golfer has a specific preference for a certain single length for his irons, comfort does rule. We do not recommend the irons be built to a length greater than 38” if possible.
