I just picked up a Storm Sure Lock from Buddies and it is probably one of the best balls I have ever thrown. I usually don't do well with asymmetricals and usually even worse with strong dull covered asymms. Not sure what it is, but I guess I just match up really well with the ball. Most people I have talked to said the ball was too early, would burn up, or roll forward for me. That is what balls like this usually do, but this ball gets down the lane and gets back to the pocket like no other ball I have.
So that being said, what is out there that might be close the the same reaction? People have told me that the Crux Prime is supposed to be a hopped up/ better sure lock, but from what I have seen it doesn't look close to what the Surelock does.
