I have tried every thing due to my slow ball speed, and the solution for me was a polyester Track Spare + 15 lbs. I also use an old AMF Cobra 16 lbs. Both balls are high gloss. I found that I needed the weight to get the ten pin out. I tried 14 lbs, but could not carry the ten pin.
So my suggestion, use the heaviest ball with high gloss in polyester..... No pancake weight blocks!
Good Luck!!
