thanks for the reply, that is a great start. I am a high track bowler with a moderate rev rate. I'm not a huge handed player. As I mentioned, I'm mostly interested in these because of a PBA experience league coming up this summer. I see a pretty large hole in my current aresenal. I don't really have anything that will handle oil all that well. Most of the time I'm bowling on medium condition house shots in various houses and tournaments. The flatter PBA shot with an increase in volume may present an issue with my current arsenal. We were kicking around the idea of taking the surface down on the revs as a possible alternative to the hook. But, that does not rule it out of course. We're trying to decide what is the best choice.
