Agroves,
I finally got the positive weights taken out, with excellent results. The ball had just under an ounce side and finger weight. I added a balance hole on pap to bring side weight to zero, and drilled the fingers down to zero also. Threw it last night for the first time on my fried second shift league; 276 (one "oops" in the sixth), 235 (lanes transitioned and I did not move far or fast enough), 193 (still not keeping up with transition: eight strikes and four splits), 704. This is huge on this shot. The ball no longer jumped across the back end as violently as before, but reacted controllably, with a nice smooth transition off the dry into a nice arc into the pocket. Although the strong backend reaction you described was the same I was seeing before removing the positive static weights, the only other difference between your Neptune and mine is probably pin and cg location. I originally had the pin at 6", cg at 4", with the reaction described earlier. Now the ball is set up 4 x 4, stacked, with pin just slightly above and slightly to the right of ring finger. This is a stronger drill than yours, so I can't be sure you will see the same results I did by adding a balance hole. But, after last night, I would still have to recommend it, taking the static weights to zero. Also, I did not have to ad surface to the cover to achieve these results.
