My normal shot is down and in. I swing out 2-5 boards usually between 5 and 15.
I don't get much practice playing deep because where I bowl league, I don't have to. It just seems when I get inside, around 15 or 20, I feel like I'm throwing a straight ball. The ball doesn't look like its hooking. More side rotation helped me this weekend, but it was tough getting the ball to push down the lane. Too wide and no recovery. I get the same look with some of my other equipment as well. My "length" balls are too mellow to turn, and the more aggressive balls won't get down the lane.
