Doesn't everyone realize that, as always, it depends on all the factors?
The greatest one after the bowler's release is a ball whose core has a fairly large RG differential plus the drilling. For any given oil pattern, the ball's surface and the bowler's release, a strong drilling that allows the ball's RG differential to save the most flare for the backend will APPEAR to hook the most ...
The amount a ball hooks can be fun but it is the least conducive factor to good scoring except on a Wall or a House Shot.
In the PBA, oddly enough, every guy who has come out throwing a huge hook has not won consistently without taming down the huge backend that scored so well with on his "house shot". Yet, on the other hand, really straight bowlers, like Dave Traber, have not succeeded nearly as well as you'd think they would. Those who you see on TV throwing very straight, like Mika Kouvuniemei, Norm Duke and Steve jaros, ONLY threw it straight on the TV show.
Everything in moderation seem to be THE main key to real bowling scoring success.
