i'd probably plug that too b/c the drilling isn't utlizing the strengths of the ball, it's not letting the ball get the energy stored to react w/strength.  It might move, but it doesn't do it w/authority. drill it up correctly, it will not disappoint.

I have mine pin high over ring and cg stacked at 4 1/2 x 4 1/2 after going to 1000 this ball is as just under the action now for me that i had owned. In box the cover was too over/under and that might be most of your problem, i do think you drilling is about 1 to 1 1/2 to weak. Length is built into this cover when polished up, in my case it is now pretty early and i will be hitting it with rough buff too give an extra couple of feet of length. I bowl on heavier mediums with the thickest kegel oil made, so box the ball went 55 feet revving and revving never reading the lane. I would sell this ball to a lefty and go get a backyard bully on closeout for well under 100 being you are a pro shop guy.

My backyard's even though same cover recover better on the backends than the action packed does for me. I think mallet core is better at flipping over than the core in the AP, the trick to byb is keeeping pin at finger level or higher. The cores are far more dense than advertised and the rg is lower so pin under drillings hit like wet noodles because the ball is dead at the pins.
