We do use it in some other lower stress / lower power areas.

Same here. In 2001, we had #25 in the drive. During 2003, when it was our practice robot, we spent more time replacing chain than we did driving.

We used some in our shooter in 2006 (intermediate pulley system to the shooter wheel). The rest of the power transmission there was a belt, and we never had a problem. Actually, most of our shooter/loader was belting, either for transport (timing belt driven by an FP) or for shooting (Big CIM to intermediate axle, where we put chain the rest of the way).
