tav against clutch. What do you expect with a 300LB. butt, no more ice cream and cake for you. depends on the rideing. once the clutch hooks up they are the same. after you are going the clutch stayes locked up, and they are equal. tav more moving parts to wear out. the tav on short runs or hill climbing has the advantage. 20+ the clutch has the advantage, theres drag with a belt not so much with a direct chain.
