Russell is correct. However, with pins that close to the cg, USUALLy the only types of drillings you can go with a pins located under the fingers, especially with that much top weight. Reason is that if you still put the pin above the fingers, you are going to have a difficult time getting the finger weight under 1 oz to make it legal. But, as Russell suggested, go to your pro shop and see what they can do for you. Hey, sometimes, if you are "in there" with them, they might even do a trade for the same ball with a longer pin out distance. Doesn't hurt to ask.
