we put mountain dew cans over our cims, at first because it looked cool, but i think it did help with cooling. the cims in this years robot never seemed quite as hot as previous drive's.

Unless the dew cans were adorned with fins, I can't see why it should help with cooling. Black is a better radiator.

I have seen robots that drain a battery in one match, power draw is something teams should think about.

Increasing friction also increases the amount of power that is required to turn, this can result in a large power draw. If there is a reasonable amount of performance increase that can be gained by minimizing slipping in software why not take advantage of it?
