I bowl on a 40 foot flatter sport shot, I like to use something that can get down the lane, so I have liked something thats polished up at a higher grit and can get down to 45+ feet before breaking. For me personally I can use something with a more arc reaction but it has been nothing but inconsistent from every spot on the lane except VERY straight. The longer, snappier ball I feel gives me a little more room and on our shot the middle of the lane burns out fast and the polish gets it over that. Good luck!
