KBS Wedge Shafts
HiRev 2.0 & 610
It is always a pleasure to spend time talking about shafts and fitting with Kim Braly. If a picture is worth a thousand words, then a video is worth a thousand pictures. If you want to truly understand the two new wedge shafts from KBS watch the video embedded below. The short story is KBS has improved on the original Hi-Rev wedge shaft and introduced a new model.
The Hi-Rev 2.0 will replace the original KBS HiRev Wedge Shaft. The new design is a higher launching shaft that will create more spin. The illustration below shows the difference between the KBS HiRev and the KBS HiRev 2.0. Butt to tip change in stiffness is higher in the new model. And additional loss of stiffness in the tip will create more launch and therefore more spin than the original HiRev design. If your club head speed does not generate enough spin, the HiRev 2.0 shaft will contribute to a higher launch wedge shot.
The 610 is modeled on last years Tour V design. A long stable butt section with a rapid loss of stiffness about 14″ from the tip. Tour testing has shown this design produces a lower, more penetrating ball flight. The softer tip will create enough spin to check the ball up without adding height to the shot with excessive spin. If you want to keep your wedge shots from getting blown around and you have the club head speed to spin the ball, you should test this design. The model name, 610, comes from the butt diameter. To create the design, butt diameter became a little larger as explained in the video.

This interview was shot at the 2015 PGA Merchandise show. It is worth watching to listen to one of the most experienced club fitters of our time discuss club fitting.
