I appreciate the information. Coming from an electric marker, I feel like open pump play is the coolest. I am really into the idea of having your own marker that not everyone necessarily has a clone of. I'm all about rec ball, the only reason I was actually concerned about pump play and it's variations is because it seems to already have such a small community around here that I'd hate to be that guy who has a converted cocker and shows up to face a bunch of guys who will only play stock class!
I am just fishing around for information at the moment anyhow, still need to play a game or two before I invest in a marker.
