Judging by the product photos, the 6.5" and 8" versions have different designs - depending on the material used, two legs instead of one and the way the legs are attached. The 8" version is metal and very grippy. Despite the fact that I only have one leg, this is a study, although the figure is heavy. I bought two 8" versions and am very happy with them! Avoid the 6.5" version if you can.
