Cyberphil I am shocked you would not consider MECHANIUM........Figured 103 would be locked on that for sure.
As Mickey from Rocky said "WE NEED FAST GREASE LIGHTING ITALIAN SPEED"
Speed and manuverablility is the key here. Additionally, mechanum makes it easy on your programmers gives them that "shuffle/crap" ability to get in line with your target and if built correctly provides for tremendous speed. For those who want to pin; cant pin a mechanum they always have a way out. SPEED SPEED SPEED and did I mention SPEED.
