It would be interesting if you did take all the top players and fix all their "flaws" and see if that makes them even better. Could you imagine some of these guys. I guess the question would be what do yo think the proper fundamentals are. That would be fun to talk about.
I have been watching videos lately and noticed a few things. They basically all hold the cue with the same bridge length (regular shaft different than pred shaft). and they all finish close to the same place on the follow.
Regular shaft they hold just ahead of middle shaft and finish the stroke near the middle and predator shaft players seem to have a little longer bridge finishing the stroke around 3/4 down shaft. the regular shaft players have a shorter follow after CB contact than predator players.
I haven't watched enough to say a 100% do this, but all 10 that I compared did.
