If I decide to drop to 15# equipment, should my arsenal consist of asymmetrical, symmetrical or a mix of both? I'll probably end up with 6-8 balls. I bowl in a few tournaments here and there and hope to make it to some big scratch tournaments and maybe a couple of regionals. I've got a 15# Slash coming and after I have it drilled and compare it to my 16# Slash, I'll make my decision about switching. Just trying to get an idea of what to do. I plan on building my set slowly to make sure I don't get a bunch of overlapping balls. Thanks for the help and all the comments about dropping to 15# stuff.
