To be fair mate, and this is in no way a dig, it's difficult to tell from that event how your robot stands up to spinners. Eggbeater was using hair bands (literally, they were hair bands) for belts on it's weapon and it could barely spin up properly. Lynx in the rumble at the end went through 15mm of hdpe on Fhqwhgads and went through the 3mm steel on the front of Flatulence and Spin Cycle was pushing through 10mm hdpe, that's the sort of stuff a robot has to stand up to.
