Downside is you might need to futureshine Motormaster's knee joints, since Menasor is the most topheavy combiner by a long shot, so he might not hold all that weight on his friction knees without some futureshine. It doesn't help his innate balance problems either, you still need to be on point when posing him or he'll tumble, a problem most of the other combiners don't have.
