As of when I drilled dave300 some balls he had to be careful with his layouts. He then took a year or so off from bowling. He has high speed, high revs, and high track. He bowls in a fricken dungeon of a bowling center. Beat up wood, not much oil, they would probably play like not much oil, even if they did oil them.
dave, I like the 6" pin idea, you need the length, mass bias, down below your thumb and maybe a small hole on your PAP if needed to make legal. Should be pretty long, fairly smooth.
Hey Victoria!!!! Grats on your baby!!
