I had the same problem, and the only thing that really helped me was going with more forward pitch. I went from 3/8 reverse 1 year ago, and now I am at 3/8 forward and 1/8 under the palm, and I absolutely love it. MY balls get out onto the lane, and I fell complete control over them. Take an older ball you have and experiment with more forward pitch. But make sure you are shortening the span a tiny bit everytime you go more forward.
