When driving with a skid steer system, the rapid, high speed direction changes have a tendency to make the belt jump a couple teeth, which will wear them down quite quickly.
As for stretching, as long as they aren't over-tensioned, you won't notice any stretch duting the time of a FIRST season.
As for belts for non drive base use, I say go for it, they rock because of weight and size.

I have to strongly disagree with you.
Maby you are using the wrong belts because with the Breco-Flex belts we use we have had no such problem. We have never slipped a belt during a match or chipped the tooth of a belt. The only problem we have ever had was a belt snapped once in an off season event which i still don't under how 10 steel support rods that run through the whole belt can be sheered.
We buy our belts and the pulleys from the same company so that they mesh perfectly.
