When I think of a ball joint, I think of a ball fitting into a socket. In this case, it is two pegs attached together at hinge. Honestly, I don't see how Sideshow will be able to tighten the joint in its current form. I performed the superglue trick (with liberal amounts) and they are still loose. If Sideshow could just use a double ball joint, like Hot Toys, does it could save us all a lot of headaches. Other joints on the body, I was able to tighten with screws. The screws simply weren't put in all the way at the factory. The joints I couldn't tighten were the elbow and knee joints because they are glued together.
Have you guys tried using a Hot Toys stand for the troopers? I have found that they work better than the Sideshow stand because of the belt and cylinder. Maybe Sideshow should use this type of wire stand for the troopers. I know the under hooks might look strange on figures with pants, but they look great with these armored figs, including Clone Obi.
