I am familiar with twin-disc setups on a different marque and there were complaints that the clutches can be hard to modulate to produce a smooth start from rest.
Im sure some are, but the mcleod rst I have is not abrupt or difficult to modulate at all. Have daily driven it with that clutch and stock engine, and now with heads/cam +4.10 gears. Chatter from the twin disk is the only complaint, some have it some dont.

My Monster 3 disc is pretty easy to drive on the street. It takes a couple hundred miles for the clutch to wear in, and those first few miles the engaugement is pretty rough.
Now - it just acts like a clutch.

Having driven cars with the early McLeod twin discs and Tilton 3-disc road racing clutches... those occupy more the realm of light switch connecting a bomb to your wheels.

Knowing I will be roasted by the monster donkey-CAM crowd... and off-topic for this thread...

It is great!!! pulls great through 2000 to 4000 rpms, torque is just thick, then rushes to 6500.

I had a friend riding with me asking me how much boost I was hitting... hmmm... the car is NA buddy.

3:90s going in mid-May, with a Monster twin-disk and 20lb flywheel.

To the OP...

Did you make a decision?

I ran a C6\ZO6 clutch for 8 years on a head\cam 383, and was completely happy with it.

I just got\received a Monster Twin-Disk... installing this week. I will post back about how it goes... suppose to be long lasting and shift very near factory.

Looks very well made...

I had a monster twin in my Camaro and absolutely loved it. Zero chatter, very little effort, and it grabbed like nobody's business! I am thinking to do the same on my Z06, or adding a Mcleod RST

20 years ago the RST was a pretty brutal clutch, I think they've done some updates to the design since than.

The RXT/RST are no longer that way, not at all. I have an RXT on my ‘02, with lightweight flywheel, installed about 8 years ago, and it’s very easy to drive. This is on a fully built heads/cam setup with a somewhat aggressive cam, CamMotion Titan 4. It’s not grabby at all, even the more aggressive RXT, and there’s only occasional plate rattle in neutral. It’s been a fantastic clutch.
