Hi Tony,
Based on your description and speed, I'd suggest that you try to lay this out with the pin in line with or below fingers with the CG kicked out right to have a 10:00 to 10:30 angle. Pin under would be better for you if you could. This should help the ball stand up quicker in the midlane for you to get a good reaction on the backend. I saw your profile and it's longer(coverstock) then the balls you currently use now. Hope this helps...good luck.
