I've been there the last 3 years, and the one thing I can say is the shot changes fast. On fresh it starts out with an OOB outside of 10, and seems dry in the middle. If you pull a shot you'll crossover, and if you swing it outside it's not coming back. I've thrown and seen a few gutterballs by otherwise high average bowlers. But, when the shot breaks down after the first squad the lanes dry out quick. Generally it's a tough shot to score well on though. I've had a few big games out there, but it's hard to put together a big set because of the transitions.
I've always found the approaches fine, a little slick maybe, but I don't mind the extra slide.
