I have one - 55lbs @ 28. 68ntn.
I have no problem with it, although I'm sure you'll hear some criticize it. I asked the same question before I bought one from a classified on here, and the replies were mostly pretty negative. Hand shock that would dislocate your shoulder... things like that.
But I have experienced nothing of the kind. Mine shoots fine and I like it. Especially for what I paid for it!
I'm not planning to hunt with it this year because I'm trying out a new Dryad blank that I finished. If the Dryad goes kaput, though, the Wildcat will be the one I grab.
