Its great to sit back and let you guys debate an issue. I learned something from you all. I know it was an open ended question Jeffrevs but that was just to get some feedback, thanks. I have a storm ace and I love the way it backends on the right condition. I like symetric bowlingballs. I like the stability. I didn't think asymetric would work for me. Now that I know they will, I was thinking about getting one for the heavier oil shot. From reading your profile Bob Hanson, your game sounds similar to mine and I think I read that you prefer symetric equipment. Its just an experiment, I'll be sticking with symetric bowlingballs in general. I think my ball driller is competent, his explanations aren't as good as you guys though. Thanks
