So I bought a Brainstorm body on eBay to fix up. Overall, he's in pretty good shape. However, one hip joint turns very easy, and the other is extremely difficult to turn. Unfortunately, the way he was designed, you can't really remove the upper part of his legs from the torso. I googled this and saw a few others complaining about same issue. Is this a common problem with all Brainstorms, or should I look for another body?
