Me personally, I like a cable clutch more than a hydraulic clutch. It gives better feel but a hydraulic is a lighter and easier to drive. I could go on a rant about that but I shall refrain.

Anyway, I've seen kits out there to do some sort of cable<==>hydro conversion but I forget if it was to put a hydro transission in a cable car, or to put a cable transmission in a hydro car.
