Very Large Pin (8)

Question
Hey there guys, I'm writing from Mexico looking for someone to help me, I've just bought a discontinued dynothane vendetta bowling ball. but the surprise was that it has an 8" pin (Yes 8" from p韓 to cg) I just don't understand physically this at all, i mean, then where is the psa or mass bias ? I've been figuring out how to drill and wondering if you can help me out with this, thanks a lot.
I am tweener rigth handed 350 rpm's 15?axis tilt, 17 mph bowler.

Answer
Fernando,
If it is not obvious you bought a defective bowling ball (great for full rollers though). The key to your ball may be that the top weight will allow the ball to be drilled normally using the pin as the indicator of the top of the weight block, but that the imbalance is bottom weight instead of top weight. Deep holes and a weight hole would be a problem.

If there is a lot of top weight, you need to drill the ball like the weight block is flipped upside down, using the Center of Gravity (CG) as the primary starting point for the layout, but guess to where the bottom of the weight bock is (probably the cg will be close). Don't end up with an illegal ball.

Good luck, you might need it!
