Quoting myself to emphasize the line that matters.
Ditch the McLeod. I used to run that clutch (details in my build thread) and the engagement window is just odd. It was ok but I was never really happy with it. McLeod does sell a good twin but it's the full fingered style not the long style three finger.
The full fingered is supposed to be great (agreed). Not nearly as many people have played with the three finger version (AndrewB70 was one, he repeatedly told me to "ditch the truck clutch"), BUT now you've heard of folks not liking all McLeod twins.
My beef with the three fingered version is that it has almost all of it's disengagement in the first 1/4" of pedal throw. There's no over centering action on the stroke so the pedal pressure just rises steadily while the grab just falls off FAST after after any pedal movement.
It's like as you step down engagement goes:
100% 30% 20% 15% 10% 5% 0% over the course of the throw
vs. a typical clutch which would be more like:
100% 100% 80% 50% 30% 10% 0%
Modulation changes dramatically depending whether you're on the power or not and it's just a weird odd ball clutch. You breath on the pedal and it loses a huge portion of it's grabbing power. Oh and mine was still running the organic material and liked killing slave cylinders. To the OP, if you can, call McLeod and see if you can exchange for the more modern version.
You've got a great start on a killer car. Don't sell yourself short on the clutch. It's something you'll interact with every day you drive it so it's worth getting right.
