I replaced my clutch, pressure plate, and flywheel after a turbo upgrade years ago and originally went with a 4-puck unit. Great holding power, but not the smoothest thing for daily driving. I am now using a 6-puck disc which is smoother than the 4, but still not a stock "feel" by any means. It takes some getting used to, but *can* be driven smoothly. It has a very "on" or "off" feeling, though.
That said, I agree with Candles and would not upgrade unless you are considering a major increase in power (I am running in the 300+ HP range). The daily driving tradeoff may not be worth it. IMO, if you want a little more holding power and have things apart, go with a heavier duty pressure plate (for more holding power), and a stock clutch disc (for better driveability).
Rumors of my demise have been greatly exaggerated.
