Help- can anyone give me some advise on drilling layout for 14lb ball? I am currently bowling on synthetic lanes (amf, UGH!), my average has dropped from 216 to 206 in the last 6 weeks. No carry! 25 to 30% pocket strike carry, 55 to 60% 9 counts. Lanes are top hat shot with buff to 28-30 feet, shimmed from 4 to the gutter, no oil. I have ball speed of 16.5 to 17mph and above average rev,s 43/4 up1/2 pap. had to go to 14lb due to tendonitis in right elbow. i am leaving lots of 7 pins, and lots of 4's, and 9's. any help would be greatly appreciated! I am getting serious over/under reactions all the time!
