Ok I am getting a Roto Grip Neptune and need some suggestions on how to get lots of lenght and a smooth arc to the pocket. I am a high tracker, high rev bowler and most balls i have been throwing like my Low Flare Stinger pearl drilled pin above ring cg kicked out, have been too strong off the break. So guys give me some good drillings that will work. Thanks in advance.

I would try putting the pin 2-3 inches from PAP and the cg near the center of grip.  This layout allows for a much smoother transition down the lane and tames the breakpoint.  With your track and rev rate, you will still get decent overall hook; just a smoother breakpoint.
