Well, im in no way an expert (as ive only had my X-men since November) but i have followed the post on here (there are lots and lots). A lot of people "remount" wolverine so he slightly more to the right and out of the beast shot path ever so slightly. More recently the concern on all versions is that Wolverine is a bash toy that takes lots of hits and breaks in 2 areas mostly; the back where the screws mount to the post and in the in the front of his belt where the ball mainly hits. Ive only experienced the back issues myself, but have twice. As these machines are basically out of warranty now, replacement wolverines will cost yah nearly $100 a pop.
