Rated 5 out of 5 by from consistant performer I have used the 65 'competition' series for several years repairing clubs for my fellow golfers and have always had very good results and compliments on their performance. Recently, a friend asked to have his steel shafted Callaway irons replaced with the Competition 65 shaft to swing between regular and senior. I accomplished this by down-stepping the 'regular', and it fits his desires perfectly.

I have a set of Taylormade SLDR irons with KBS tour shafts.Would this be a good replacement if I want to go to graphite ?

Asked by: mike45
The Competition Series shaft is a good shaft and it will fit the SLDR irons. As an R and S flex it is designed to create a mid trajectory. It is a big weight difference from the KBS Tour shafts and it will come down to how well this weight change fits you. It can always be good to try 1 or 2 shafts first before reshafting the whole set to make sure they will work for you.

Is it possible to make the tip .355 taper ? I am looking for a good graphite shaft to replace steel shafts in Titleist AP1 714 irons (4-9,P,W, - 8 shafts). If not, could you recommend reg. flex graphite w/ .355 taper tip to use in this application ?

Asked by: JoePuck
We could special order the Competition Series Graphite shafts from UST with a .355" taper tip to fit the AP1 irons. You would need to contact our Customer Service at or by calling 1-800-848-8358 and they can help you with the special order. Another shaft I would recommend that will fit the AP1 irons is the Xcaliber (AS0028) which is available in a .355" taper tip. It is a very good inexpensive shaft.
