I have just recently drilled a AU79, 4x4 pin over ring small balance hole
1" past val. The Au has plenty of length and a good amount of recovery, but not enough to satisfy my normal line. I put it on a spinner, with the track side facing up and lightly scratched the cover with a 500 grit abralon pad, then applied 2 coats 2000 degree polish over it. Now I get the reaction I was looking for, shot 717 Wed nite for the first 3 game set thrown with it. I was able to stand 34 loop it out to about 10 at the break point and back to the pocket. Good ball with a great midlane read, very angular to the pocket, most of all I only left 2 tens all nite. I have heard rumors about a break in period, but being the only one in my area throwing one I can not verify it as of yet. With a few more sets on it if I see a difference I'll let you know.
