My pro shop guy had a Sync seed ball he received and I had him drill it up Thursday right before league. I drilled it 4x4x2 and this rolls very well for me. I shot 757 with it and that was with a pocket 7-10 in the 10th frame of game 3. I had 14 in a row at one point between 1st and 2nd game. It is very continuous and on light hits it was throwing pins all over the place!! I look forward to putting some games on this bad boy..
