The KBS Tour 105 Constant Weight Taper released in August 2015. The label looks much like the KBS 105 Parallel that is offered in the 2015 Taylor Made RSi irons, the shaft is not. The KBS Tour Taper 105 is generally stiffer and has a firmer tip than the TaylorMade only KBS 105 Parallel Shaft.
My fitting experience has taught me that the 105 to 115 gram weight range is the best fit for most amateur golfers. My understanding from the tour fitters is that this range is rapidly gaining traction among professional players as well. The KBS Tour iron shaft profile is not new. It is available in two 90 gram versions and the ‘standard’ version that ranges from a 110 gram R to a 130 gram X in 5 steps, 5 gram increments. The Tour 105 overlaps that range as seen in the table below. It comes in 5 gram increments, a 108 gram R, a 111 gram S and a 117 gram X. The 111 and 117 are much the same as the same weight KBS Tour shafts.
Now look closely at the difference between the profiles of the short and long irons in the two sets. You will see a flatter short iron vs long iron in the C Taper profiles than in the Tour set. This is what is referred to as a flighted set. Neither set is intentionally flighted, but one would expect the CTaper Set to deliver lower, more piercing short iron trajectories than the Tour set. And this is precisely why it is important to know set profiles not just 6 irons when fitting irons. The KBS Tour model will flight high throughout the set while the C Taper will offer some assistance in launching the long irons while keeping the short iron trajectories lower. Which is best is simply a function of your individual style. Knowing the profiles, your fitter can match you to the iron set that enhances your game.
