IMO, it sounds like the ball may be burning up when you miss right...
I would bring it to a 2000 pad and then polish it...
If your playing that deep, then to me the lanes are a lighter oil pattern...If so, a polish ball will give you the length you need and bring up the backend...
The problem may be, that since you may be more of a stroker, playing this deeper line requires you to maintain your ball speed... If you get too fast, you may hang, and if you get too slow, you may punch the nose..
Most strokers have a problem sending a ball out for fear it may not return... So they either lay off the speed or lay off the hand...
So since you are out of your comfort zone, maybe move back a Little right and try using the ball polished...
