Rob must have drilled it...he's a Track guy. Anyway depending on how it's laid out and I know you have plenty of hand and ball speed to use more hooking equipment. I think, I'd think about a symmetrical cored ball with less flare to tame down the backends. I know, you do like skid-flip balls though. Rob may think different.
I'd hate to see you spend big $ on another Rule just to have the same basic problem. The Goo coverstock and that core mean to me lots of hook especially on clean back ends. When I subbed on a Tues. night Village league few years ago I used a sheen type particle ball with not a lot of flare up the track about 12 at the arrows to 8 at break point. Particle smoothed out the over reaction.
What else do you have laying around that you could experiment with?
FYI....to all these are houses in Madison, WI.
