But hook doesn't automatically equal higher scores. If that were the case, every high level bowler would be two-handed/no thumb. If rev rate were all it took to win, guys like Robert Smith would've won 100 tournaments. Yes, in certain environments, rev rate and speed are an advantage, but that isn't always the case.
If Smith was 25 today, he would be running over the tour. He was more accurate and repeated shots better than a lot of these younger guys do. Rev-rate and ball speed IS more important than anything on tour these days, just look at the numbers, and who is winning. You really think Jesper is splitting boards hitting a dime at 45 feet??? Ah, no
The oils today create more natural hold downlane, than what Robert had, when he was bowling on tour, plus there are higher volumes as well.
As a side note, hook potential is how you generate higher entry angles, that allows the ball to have a wider pocket, and use the side boards to also strike, whether it be done with the ball or hand.
