Because IMHO, everything else is a complete waste of time, unless you have no inclination to learn about clutches. If you don't want to learn then get a center force. If you want to learn that you would fast find out why I say those other clutches are junk.

Simple question. We've already heard your opinion on the vast majority of clutches out there, and since they're all junk or a waste of time let's hear about yours.

Clutches are not that complicated. If I can learn enough physics to finish an aerospace engineering degree, you're not going to lose me explaining your clutch set up.
