On cores with .020 or less differential, does pin position really even influence reaction given there is so little flare to begin with? I see no difference in reaction or track flare with my hammer urethane balls regardless of pin to pap or pin buffer distances.

How many balls have less than .020 diff? Only one I can think of is the tropical breeze. (I think that's right) but lower differential means less influence the pin has from 1 layout to the next.

The Twist by Brunswick is .018 in 15lbs. Don't think there are any others though.
