quote:When placing a pin @ 6 3/4" from PAP you take the chance of the ball track reverse flaring because it is too close to the track. I would recommend not going past 5 1/2-6" to be on the safe side. Same with going pin axis, you have to be careful. You can place the pin 1 1/2-3" above the fingers to create length but you again have to be safe as the track can flare over the thumb by raising the bow tie too high.Also, surface is going to dictate length as much as anything. --------------------Ric HamlinPacific Northwest Product SpecialistBrunswick Bowling
