If you design the drive train correctly, you should never have any problems. (use large sprockets, dont have any slack, have chain guides)

We have been a high traction robot for two years with our 6WD system. The secret is the larger sprockets, it allows for more chain to go over a single sprocket than a smaller sprocket, which would give you more torque. Think of it as a bicycle, if you put your bike on the highest speed, it causes you to push harder (which also puts more tension on the chain), if you put it on a low speed, there isn't as much tension on the chain. The same applies with using 2 large sprockets or 2 small sprockets. The weight cost to go to larger sprockets is minimal, and will save you at competition.
