I knew a guy that had one of those in his supra and in traffic jams he'd have to wait for the car ahead of him to move pretty far ahead so he could let off the clutch so he wouldn't run into him. He hated it.

I have an ACT XT-SS (xt) pressure plate and (ss) clutch disk and I love it! It's a little harsh and doesn't have hardly any slip, but I wouldn't go any more extreme than that.
