Yep, evidence that tech has helped. I have agreed from the beginning. That in no way proves that only tech has increased distance over the years. Only that it is one factor, which I have agreed upon from the beginning. Is that really hard to understand. All you are proving is that tech has played a factor, not that it's the only factor. Causation.. Hard to prove without a lot of data.Three years ago they had some Tour pros hit Ben Hogan’s old driver and took Trackman readings. Jason Kokrak, one of the Tour’s longest hitters, participated. His drives averaged in the 260s (with modern balls). But, but, fitness ....
“Launch angles with the throwback club were much lower, around 9 degrees instead of Kokrak’s usual 11. Spin rates were dramatically higher, 3,100 rpm versus the usual 2,200; thus, the curve balls everyone was hitting. Ball speed was 164 mph against the 179 Kokrak gets with his Titleist 917D2. As for distance: Kokrak’s tournament roll-included average of 304 yards contrasted with his max carry of 271 with the old club. Of his 10 drives, most flew in the low 260s.
The size of Hogan's driver compared to today's standard club is striking.
Kokrak, from Warren, Ohio, 6-foot-4 with a program weight of 225, looks like he could have played offensive line at Ohio State.”
