The True Temper GS75 – touted as the world’s lightest steel shaft – was one that I had put an asterisk next to it when we first heard of the introduction from our True Temper representative. While shafts of slightly higher weight had been made in Japan since the earlier part of the 1990’s, those shafts were dedicated to golfers who possessed low clubhead speeds (A-flex offerings), yet the GS75 was coming out of the block in standard R and S flexes.
For the catalog we like to obtain samples so that we may include them in the annual Shaft Fitting Addendum as well as additional information in the catalog regarding swing speed ratings. The static testing is done primarily in the winter months to measure the frequency, torque, flex distribution, etc. However, being located in the Midwest, it takes longer to field test the products once the weather decides to cooperate.
The GS75 on paper will appear to be very flexible, as evident in the data laid out in the Shaft Fitting Addendum. But as I have said many times over the years that you need to compare shafts of like weight in order to obtain a true apples to apples comparison. Well unfortunately the GS75 does not have any peers as the closest shaft would be the Apollo Spectre Lite weighing in at 10 grams heavier at comparable cut length.
Just by bending the club with my hands or waggling the club, it confirmed that this shaft was indeed more flexible than any I had tried, including many L-flex shaft. However, applying the acid test – hitting balls and watching the ball flight – I was pleasantly surprised. The shaft didn’t feel flexible at all. The S-flex model I made up for me was honestly as stiff as the majority of S-flex steel shafts, even knowingly cognizant of the fact of what all the data indicated.
I had a fellow golfer at the range hit the demo club. His Ping iron was equipped with a CS Lite S-flex (very similar to the True Temper TX-90) which he hit side-by-side. I only told him that it was an S-flex club, but he still had to look at the label to confirm. I asked which of the two felt stiffer and his response was the GS75.
We all have a lot to learn not only about shaft fitting, but shafts in general. I remember years ago when Royal Precision came out with the Precision FCM Lite (pre-Rifle days), there were frequency-matched to be identical to their heavier counterpart. While the FCM Lite was no where near as light as the GS75, I do remember what a boardy-feeling shaft it was compared to the standard FCM shaft, even though they had identical frequency reading and theoretically should have felt the same.
I guess my point is regardless what the numbers indicate, if you are looking for an extremely lightweight shaft, but like the control you get with steel, the GS75 might be for you. This is a shaft not to go by the frequency numbers (deflection or any other information that can be derived from any static testing) and taken off your list of shafts to try because of it. As indicated in True Temper’s product literature, the ball flight is indeed higher too.
