I have an extremely high track, high speed and high revs and I am looking to drill a ball (green gargoyle) to get some extra length and an even(tamed and predictable) backend. Last time I drilled a ball to do so, I went with the pin over the bridge. This resulted in the ball rolling over the fingers/thumb once it got down the lane and flipped. Can anyone offer any drilling suggestions (pin, mass bias position) to keep the ball off the fingers and or thumb and still get it to do what I specified above? Thanks in advance for any help.
