I've actually been a huge fan of the tripod version; and while I may see what others think, I still believe it works out well. As far as I'm concerned, I've always seen the back, uh, "arm" as the support while the other two are used for combat. If Tripod Megalon could gyrate his head, it'd be really crazy for Megalon to shift what arms are used for attacking and which one (or ones) would be used for support.
