Ben half of those set-ups are identical to one another. Why you need a T-Minus style lifting arm AND a Toro style lifting arm, when they are ESSENTIALLY the same thing, is beyond me. Likewise, why you need two Tazbot type arms, I dont know. You need to think this over.

My vapourbot, Cyclone Force, had 5 interchangable weapons. But since having a rethink, Ive narrowed it down to three.
