What clutch to buy?

I dont get why so many 4-speeders are afraid to remove the clutch assist spring, and are willing to put up with a 3-finger pressure plate with its attendant bionic leftleg requirement.Its not that big a deal to remove. And a diaphragm pp is sooooo nice. Especially at parade time. I wasnt that keen on the Dual Friction disc though. I put a factory 340 disc in. It doesnt last nearly as long. But its smoother, easy to modulate, and easy on the flywheel. Just replace it as soon as it shows signs of distress; theyre not expensive. Oh, and yes Ive sorta ripped the hubs out of a couple of them at 430hp. I was able to limp it home.
