just got this one drilled up and man is it a hoss! This ball came to me with 1 6/8 top and 1" pin. Me and my driller desided to lay this one up Left Pinky finger leverage. That was just what i needed after throwing this ball let me just say it flat out hooks, but not early, it stores all of it's energy for the backend and then makes a tremndously sharp move. The first time I threw the ball i chopped the headpin off the rack.
If you were to buy one of these i would NOT suggest a stronger drilling than i have on this one as this ball stores up so much for a huge pop on the backends.
All in all this is a great ball with this as my strike ball and my messenger for spares i should be unstoppable this year. I may have to drill a large hole in my track area to help tame the backend a little, i'll post an update if i do that to let you know what it done.
