If your hand can't do it, then the ball won't help a whole lot.

There are 479 balls with great backends; in fact, most, but not all, balls are designed that way. Pick almost any mid-priced pearl and it will or should do that,  unless you are highly rev-challenged.

Oh, by the way, the greater the backend, the less control you'll have over the ball; meaning the more splits and washouts you'll throw for every strike that that huge backend will get you.  One factor goes hand in hand with the other.

And life goes one ....

Danes already suggested the Silver Streak Pearl which I was going to suggest, based solely on the reaction from my original version of this ball.

I had the pleasure of seeing a T-Road pearl in action last week, that ball has AMAZING back end.  It was outhook most of what was being used in the back end and killed carrydown.  Very nice carry with some serious movement.  It looked great on the lanes but I worry about control?  If you're looking for violent back end though, look no further.
