I just picked up a fairly complete VT-8 at a great price. Unfortunately it was missing the belt on the Comet 30 with a 6" driven. Reading around it seems that belt size is critical. At $30 each for a good belt, it would be nice to get it right on the first belt. If you have a VT-8 please post what belt you run and how you like it. If you have had a bad experience with a belt, let's hear about that too.
