I've got a complete OEM clutch setup with a Clutchmaster 4 puck disc, so 2 discs. The 4 puck mixed with factory bits was surprisingly easy to deal with. I recall it chattered slightly at times, but had noticeably more bite. I was willing to DD it, but later upgraded to an OS Giken super single. The whole setup is in good condition, $50 plus shipping for the lot. Email/paypal d_mozader@hotmail.com.
