I find my clutch use varies by what I'm driving. The 46 seems to prefer that I do use it, but there are times that I don't. The Kenworth we move our equipment with usually is a clutch only for starting and stopping ride. It has a 5x4 two stick setup. If I was driving that 46 on a weekly cross country freight run you can bet the clutch petal would become lonely in a hurry.
