The reason that the shoulder connector is that long is because of the Bruticus Maximus mold. I made the length similar to the Crossfire set so that every Energon(and TFC Hercules) combiner could utilize the shoulder extender. I'll look into making other options sometime down the line. Right now I only have the forearms planned and a drill attachment. I am open to suggestions so throw them at me if you have any. See my response to CodeXCDM. Glad you're liking what you see!
