That sounds like me. I also had trouble with that corner with a 16 lb plastic ball. I now throw a 14 lb plastic and I am much better at keeping the ball on target because I can get thru it better. I do have to watch the "chops" because now, the 14 goes straighter. Plus I'm in my 50's and it's much easier on my arm!
