If you bowl in a house that lays down a THS of medium, get one.

This ball is ridiculous on this pattern. I don't have anything in my bag that is as long and strong as this ball.

My Black Widow Pearl has allot more lope in the midlane and is a little less touchy on the backend than the Blue Vibe. The hit between the two is totally different; the Vibe seems to just shred the rack and the Widow sends pins everywhere, lots of messengers.

The only downside is that I was looking for a week ball and I don't think Hammer makes one. Well other than my No Mercy, which now is about the weakest ball in my bag, it is old faithful and serves it's purpose well as the first ball out.

I think he means his No Mercy has suffered a case of ball death.

If I might, I would suggest going to a higher grit finish via abralon pads rather than polish. I say this because you won't clog the pores of the ball this way and the surface will stay there much longer than polish.  For me maybe its in my head, its less "squirty" that way aswell.
