Most have enough hand to get the ball to react without trouble, enough control over their speed/rev ratio to make the ball react the way they want. Most use longer pin layouts to give them length and to keep the balls from reading the heads and mids too much.
They're not all like that, though. WRW typically uses strong layouts, a lot of his stuff is roughly 4" pin-to-PAP with the MB in the strong position or towards the VAL. He makes most of his adjustments not with layout but with surface, if a ball is reading too early or late, he switches to a similarly drilled ball but with less or more surface.
