[1625Brennan]

on 1625 we used tank treads with a twist, we added omni wheels in the front by raising the tread, this allowed us to tighten the turning radius. Only the back pulley and omni made contact while on flat ground although when crossing a defense the tread would contact making it so we had little to no issues crossing. We had originally started with Brecoflex treads although after our first comp we opted to change to our Andymark treads due to wear. The only significant wear we encountered after that was damage to our omnis, they would "jam" and not allow a roller to move after repeated massive impacts. Our whole drivetrain was ran by Vex 775Pros, 2 powered each tank tread (4 total) and 1 for each omni (2 total) Overall we are quite pleased with our choices
