So then I'll assume you are shooting predominately down around the first arrow right? That should give you quite a strong back end from deep outside. When I'm playing that shot on the right hand side I know I leave a lot more ten pins. That's when I move more towards second arrow or twelve board and that usually helps.
One of the previous comments about a plastic ball was right on the money, and I notice you didn't mention that you have one. I bought a $20 plastic Roto Grip world ball last year, polished the heck out of it and only use it for my ten pin and six pin. Damn thing wouldn't hook if I was throng it in the parking lot ! But that's what you want, something that won't hook no matter how much rotation you put on it. See if your local pro shop has any used ones and just have them re-drill it. Cheap and effective. Then all you need is to work on your accuracy.
