Am redoing a thumb on one i just picked up, for me its layed out 4x2 with the pin next to ring and hole about 5" over. Cant see any reviews where people have used that layout though.
On the conditons i see now stuff that midlanes pretty strong is good for me again. At my old centre the AR i had was a bad choice on the poor wood surface, shouldn't have to worry now about the early burn and 10 pins i was getting there. Now i think of it the pin over ring finger layout with some surface that one came with was good but i tinkered with my stuff to much then!!

Time for some REAL bowling!!!
