First option is always a smoothing out of the surface. The grey pad was a good first approximation. Not sure how much you "hit" it, but you must test it at another place or at the same place again to make sure of the reaction. Maybe the this place had too much dry backend. That will make balls overreact.
If your PAP is 5+ over, placing the pin in the middle probably made it flare too late and too much.
Then, if there's still too much backend, use the same grey pad and use it over a larger portion of the ball, still lightly. Test each change!!!! You want to clear the heads and still have enough left to carry. Careful balancing act.
You can always adjust the surface back and forth, even 4000 Abralon pad over entire ball, if necessary.
Holes are kind of permanent.
Weight hole, 6 3/4" over from center of grip thru CG should add some flare if it's big enough to affect the core. Use 7/8" -1" wide hole, 2 1/2" or more deep, if possible. Don't worry about negative side weight.
