All: I have been considering an experiment with my driver. I have been looking at the specs on newer OEM driver shafts and many seem to be in the 50 gram range with torque between 4.0 and 5.0. I am playing a 65 gram shaft with 2.8 torque, which I like, but I wonder if I would increase swing speed with a lower weight shaft. Yes, you likely would see a slight uptick in speed...
However, I am concerned with the high torque with these UL shafts. Is there any value in getting a 45 gram shaft with 5.0 torque or, 55 gram shaft with 4.0 torque? I'm not sure how many manufacturers are bang on with their torque numbers, not to mention, I'm not sure there is a standard way to measure this from co. to co.
I have a relatively smooth transition. I wonder if I will gain any appreciable distance? Without access to a launch monitor, it is tough for me to know. Has anyone experimented? I know that the theory is that high torque widens dispersion, but can an amateur golfer really tell the difference in 1* torque? Now, define appreciable...just kidding. I have a slower swing speed, Driver in the low 80s. I've tried lower and higher torque shafts, I could not tell a huge difference to them both...but, I can not say how sensitive I am. My two shafts were the Accra T40 M3 and the BB Solutions 130 A-Flex.
Lastly, I plan on trying the Graman UL440 R and the Accuflex Icon Lite R to see how they perform as well... Try them out and good luck!
