FST Pro 115 Stepless Steel Iron Shaft is rated 4.2 out of 5 by 9.
Rated 5 out of 5 by from Sweet Feel! I used the A/R flex shaft for a new set of irons I built. As I am 76, I tip trimmed for the A flex and added TT's Sensicore inserts and used Avon Jumbo Chamois grips.. The results are gratifying. No shock at impact, shots are straight and high, and longer than my Cobra SZ irons which have been reshafted with TT Dynalite Gold R300 with less tip trim to soften them a little. They also have Sensicore and the Avon grips. Since the Dynalite Gold R300 (my former favorite) is no longer available, I was looking for a sweet feeling shaft for a slower swinging senior golfer. Looks like I found it.

Rated 5 out of 5 by from Awesome I recently purchased an FST Pro 115 shaft and tipped it to a stiff flex to demo a Maltby MTF Forged 7 iron. The day after installing the shaft I took it to the range to compare it to my Mizuno 32's. All I can say is wow what a feeling!!! My ball flight was much higher and extremely straight compared to my 32/7 iron. I actually liked the MTF ball flight and feel better than my 32's. My plan for the future is to replace my 32 shafts or purchase a complete set of MTF irons and shaft them with the FST Pro 115's. I have finally found the perfect shaft for my swing.

Rated 5 out of 5 by from S/X 115 Pro review I am a 9 handicap and play about once or twice a week. I hit my 7 iron about 160. I put these shafts into the Maltby TE forged iron heads trimmed to X flex. They do play soft to flex compared to most shafts I have tried which is about all of them. I am a pretty high ball hitter with almost all shafts and these were the same maybe a touch higher. The key factor is that there is reduced backspin so the ball gets up higher fast and then just soars. I play in Texas and the wind does not seem to hurt my ballflight nearly as much with these shafts. They feel similar to Rifle shafts not Project X which I absolutely hated. I have the ability to hit the ball lower with these shafts if I want to but the natural flight is high but penetrating at the same time if that makes sense. I like them better than the Rifle line, KBS, and Dynamic Gold. They seem to reduce sidespin which has tuned my hard draw into a nice soft draw and soft fades are just as easy to hit. At this price these are by fa

Rated 3 out of 5 by from Way to soft to flex First, I will say that FST makes great products and have used them in the past with great success. for a build i did about a year ago, i wanted a midweight steel shaft and choose these. The FST pro 115 leaves a little something to be desired. They are VERY soft to flex. I ordered the KE4 SS1 club pack with these shafts a year ago and cut them between S and X. They shafts are stable, but the tip is very soft and leads to ballooning shots and a loss of distance. I eventually tried the Pro 125 in the 4 iron and PW and they gave me a much more desirable flight. If you are a low ball hitter these may be OK for you if you are really looking to hit the ball higher with your irons, But if you are wanting a more piercing trajectory, I would look to either the 115 non-pro stepped shaft, or the 125 pro in the stepless.

Rated 5 out of 5 by from Great quality at an economical price! I've built a couple of iron sets with these shafts and I've been very happy with them. They've performed well and provide the sleek look I prefer without breaking the bank. These will likely be used in many more sets to come.

Rated 5 out of 5 by from Great Shafts Purchased the S/X shafts for my Ram forged blades 4-PW. Look great w/o shaft bands, really soft feel at impact ball flight was wonderful. I used the 3iron-9iron tip trimming instructions for the set and final lengths were 1/2 in over standard. Will order again for my other sets or for clients.

Rated 5 out of 5 by from 'Feel' Shaft I have a full set of Hybrid ST irons with the FST 115 pro shafts, S-Flex. These shafts have a fantastic feel, especially for a smooth backswing. I also have a smooth down swing but fairly agressive. This shaft turned out to match my swing exactly. I'm very pleased.

Rated 4 out of 5 by from Nice Shafts I have these in S-flex in my KE4 irons. They seem a little soft to flex, but that works well for me. Trajectory is as expected. Nice feel and look. If you don't like the big labels, you can always leave them off or put them on the reverse side.

What would the tip trim be for a 3 hybrid? (ie., Bobby Jones Jesse Ortiz 21* 3H)

Asked by: Joe
You would follow the trimming instructions for a 3 iron so an A flex would be 1.25", R flex 2.25", S flex 1.25" and X flex 3.25".

I have read the trimming instructions. Once the tip trim is done does the butt end have to be trimmed to length or does the tip trim bring shaft to length and no other trim is necessary. Thanks

Asked by: steve
Yes once you tip trim the shafts and installed into your clubheads you will need to cut from the butt end of the shaft to your finished club length.

What shaft should I use for my ping g25 hybrid?

Asked by: Golfmoron
We do not stock any .355" taper tip hybrid shafts. You could use a .355" taper tip iron shaft. In a steel shaft the True Temper TT Lite XL (2XLI) could be used. Also the True Temper XP 95 could work well. If you have a #3 hybrid make sure you purchase the shaft for the 3 iron and if you have a 4 or 5 hybrid purchase the 4 or 5 iron shaft. http://www.golfworks.com/true-temper-tt-lite-xl-steel-iron-shafts/p/2XLI/ http://www.golfworks.com/true-temper-xp95-steel-iron-shafts/p/TT0101/

Will this work with my ping g25 hybrid?  

Asked by: Golfmoron
No the FST Pro 115 steel shaft will not fit the Ping F25 hybrid. The Ping G25 hybrid uses a .355" taper tip shaft. The FST Pro 115 shaft is only available in a .370" parallel tip, which is to large to fit the Ping Hybrid.

I play KBS Tour R taper tip currently. I like the weight and feel, but want to have a slightly higher ball flight and a bit more spin with a new irons that takes parallel tip. Should I go with 115 Pro step less or 115? and also which flex?

Asked by: Andre112
The FST 115 stepless or stepped cut to an R flex will play more flexible then the KBS Tour R flex by almost a full flex. You could probably cut the 115's to an S flex. The 115's test and play more flexible then what we would call normal. The 115 Stepless tests a little stiffer in the tip and lower part of the shaft compared to the 115 Stepped and this could help keep the ball flight from getting to high.

I have a 4 handicap with a driver swing speed of 105-110 mph. I have a high ball flight. I am going to buy the MMB17 irons and would like to know what would be the best shaft to buy.

Asked by: Hman
If you are wanting to lower your ball flight or do not the shaft to contribute to more trajectory, and want a standard weight shaft, you should select a low trajectory option like the True Temper Dynamic Gold. If you already hit the ball high I assume you do not want a high trajectory shaft. Another option could be the Nippon N.S. Pro Modus 3 Tour 130 or 125 options. Both are mid trajectory shafts. The KBS Tour is also a Mid trajectory shaft and might be worth consideration.

I play c taper lite 110 stiff now and really enjoy them. Would like to build a set with FST 115 Pro. How do these shafts compare, flex and flight?

Asked by: Greanbay
I would tell you from testing that the C Taper Lite plays a little more flexible then normal but the FST 115 Pro plays quite a bit more flexible then normal. At least a full flex if not a little more and because of this should flight the ball higher then the C Taper Lite's. Because the FST Pro 115 is 43" raw length .370" parallel tip shaft you would have the ability to adjust the tip trimming to make them player truer to flex. The 115 Pro should finish out being a little lighter weight then the C-Taper Lite shafts as well.
