Surprised by the question "how strong" because BTM rated it a 9 on the Dry pattern for both the Stroker and Tweener and did not even test it on the Heavy Oil pattern.

I bet you it aint stronger than my rude dude at a fraction of the cost.

If this ball is as strong or stronger than the first blood there is no way you could use it on drier patterns

Im surprised everyone is saying it's that strong. It hooks a lot in the back on a ths but it's very clean and i could see it being a dart on heavier oil. I'm more matched than my teammate i drilled one for but his goes really straight we are gonna make a surface adjustment for next week. Mine covers more boards than my sigma sting but it's a lot cleaner and is just more in the back part of the lane on my medium volume typical house shots.

The Bad Ass seems like a pure medium oil lane condition ball. But Hammer already has plenty of other balls currently out for the same condition that perform just as well it seems. I like the B.W. Legend a little more than I like the Bad Ass right now so I'll be sticking with that. I'm still on the market for something on heavier oil conditions so I'll keep a eye out for their next release. One of the balls in my current line-up would probably have to bite the dust because I personally already have balls that fill the hole that this ball is made for.
