I may just get the McLeod RST.
I'm about to finish up installing my newly rebuilt 23 spline trans with a McLeod 260123 clutch and 360820 PP. It's a Diaphragm setup. Once it's done I'll let you know how it feels, I'm HOPING it's this weekend.
I had a Centerforce Diaphragm in there before, and the pedal feel was very stiff. The Overcenter spring was removed, but I found that the entire linkage/z-bar setup was totally hammered. It was even missing the washers on the ball stud attached to the frame. I'm guessing with all new parts it's going to be a lot smoother and easier to push in.
After talking to a few people I ended up cancelling the rst and going with the 12" pressure plate with a single disc like you
