bowlingforfun,
I hope you took what Greg said seriously. He is right. But let me take another approach. Do you want another ball as an alternative to your Depth Charge? If that is true, then either the Xtreme or the Vertigo will suffice and they are nto that different from one another. One is the replacement for the other. Or you could get another Depth Charge (if you like that ball a lot), drill it stronger for an earlier roll and adjust the cover if that turns out to be necessary. An Ace is also analternative; drill it stronger than your DC and adjust the cover with a nylon pad, as Greg suggested, if it istill nt strong enough. ANy of these possibilities should work.
