@jonathanrwall. Are there many guys using c-taper KBS shafts in their irons?
KBS's C-Taper is a low-spinning, low-launching shaft that ranges in weight from 110g to 130g — depending on flex — and is a pretty popular model on the PGA TOUR.
Chris DiMarco, Retief Goosen, Peter Hanson and Pat Perez are some of the notable names currently using the shaft at the moment.
If you have an interest in using C-Taper but can't swing it as fast as a TOUR player, KBS recently released a C-Taper Lite shaft that has a similar feel and efficient energy transfer as the original C-Taper. The difference is the Lite version has a profile that's much easier to use for players with slower swing speeds.
The week before the U.S. Open, six players switched to R1 Black at the FedEx St. Jude
Classic. That's a pretty impressive number when you consider 32 R1 drivers (white and black combined) were in play last week and the black version was making its PGA TOUR debut.
You almost never see guys mess with their bag setup the week of a major; however, two players decided to put R1 Black in play in the days leading up to the first round of the U.S. Open. Jason Day requested a driver on Tuesday and tested it on the range and course Wednesday before putting it in the bag.
Day picked up about 3-5 yards, on average, with the new driver. The slight increase in ball speed and club speed — which led to the increase in distance — is interesting because aside from the new paint job, the white and black drivers are identical in performance.
Former British Open champion Darren Clarke also switched to R1 Black. Expect to see more players test the driver and possibly change in the coming week.
