You guys are raising good points.
Flex, who knows. The pdf he sent me says Ping Stock shaft. I play a TM stock Atmos R flex that tests as an X flex, lol. And it's the best driver shaft I've hit in a long time. (The lower half is soft.)
Roll-out. Yeah they are obviously using the hard ground setting. In any event, if he really does pick up 12 yards of carry at a lower launch, he's going to get more roll-out than he used to. Heck I would pay $500 easy for 12 yards of carry.
Launch angle. It looks like with his mechanics, to get 3-4 more degrees of launch would probably take the spin into the mid 3000s. From what I'm seeing on Youtube and reading in the last year or two, it seems like the trend is to accept lower launch in order to get the spin down. I recall Wishon advised to do the opposite, to ignore the spin within reason, in favor of the LA. I bet the OEMs have a better handle on this. What are you guys seeing?
It makes me want to try some flavor of low spin driver. My hits cluster around the middle of the face so I ought to be able to get away with some less forgiveness. But I don't want to! lol I still have that one out on the toe once or twice per round.
