FST 90 Steel Iron Shafts is rated 4.8 out of 5 by 6.
Rated 5 out of 5 by from Great shaft at a GREAT price! I have been using this shaft for many years, especially with customers who maybe are playing graphite today and would like to try steel again. It is so smooooth and consistent to build with. I just built my last three sets of Tom Wishon Sterling Single Length irons with them at 37" and they pair VERY well with that set. Only down side is that you can really only tip them to an R flex at best, so if you want a S flex you would need to look elsewhere, but most of my customers at this weight are not looking for a S or X flex, so it REALLY hits the mark for them!

Rated 5 out of 5 by from I could not believe this Shaft I bought a set of Amp irons and they had these Shafts in them but had been cut off. I have always been a KBS or steelfiber Shaft. I have a set of Cobra forged pro muscleback heads. I thought I would see if they would fit. I called Cobra and ask was my heads 355 T Tip and they said yes. I tried one anyway. I am 69 and have a 2 HCP. They did fit. They were FST 115 and when I got to range I hit some balls and said where have you been all my life. They hit and felt so much better than the KBS 90 R. Birdied 5 in a row. What a shaft. Golfworks has always had my business and I ordered a set of the 90 gram FST. The FST 115 got me at least 10 more yards!!! Can t wait to see what the 90 grams will do!! WOW!! Thanks FST!! David Potts!!!!!!

Rated 5 out of 5 by from Expectations Met I was looking for the higher ball flight with the soft feel of the Maltby Heads as well as distance with the regular flex. As these are not my primary set, I also wanted to stay within a fixed budget. All of those have been met..The ball flight is a little lower then my other irons (Shafts- XP105 S300 @ 24.99 ea.). I have built clubs(Stiff and Regular) for friends before and they really like those shafts. A great shaft....

Rated 5 out of 5 by from FST90 Steel Shaft I replaced the shafts in my wife's irons which were too heavy and wrong flex. She now hits the ball higher and straighter with less effort. The FST 90 was a better choice than any of the graphite options for irons. I soft stepped the A/R to make them closer to L Flex.

Rated 5 out of 5 by from Great Product I got this shaft because my 7 iron shaft snapped. I was impressed with the performance of the shaft. I thought that the ball flight was nicer and the club performed better than before. I felt like the ball flight was better.
