I have tried both, the 6 puck was a little chattery on engagement & the mileage wasn't that great, wore it out in like 20k. After I have switched to the carbon-carbon -- I am in heaven, wouldn't change back. & don't forget, the carbon- carbon includes the flywheel -- so you are getting the entire clutch kit & flywheel for $3k vs ~$1200 for lightened flywheel & max 6 puck.
