Typhoon That was the whole Crux of the video. I know you said you’re skeptical which is fine. But the whole video is about why people with slower clubhead speed cannot optimize their ball speed with a conforming driver head.
I guess my point is, if I swing a certain speed , say 90mph using a conforming driver and hit it in the center then my ball speed IS maximized for my SS. Yes, I understand that at slower SS a conforming driver isn't flexible enough to get all the yards I could with a non conforming hi cor driver, But IF I want to stay conforming then a center hit with my SS on a conforming driver IS maximizing my ball speed for my SS, unless I want to cheat. I totally understand what he's saying, I guess I just got hung up on the "maximizing your ball speed for your SS" thing. It's not that you're not maximizing your ball speed, it's that there is something out there that can give you even more ball speed , if you don't mind it being non conforming. You could just play Bandit or MG Senior golf balls too.
