I personally have an ACT streetlite 12 pounder with a ACT HDSS clutch kit (both for a Z6, slightly larger clutch). I love my setup, revs nicely and isn't too hard to engage, and never slips on me. Stef and Marty are both using an Exedy kit with a OEM replacement clutch for the CRX with the Exedy 11 pound flywheel, and I also like that. One of my friends had a Clutchmaster stage 3 and a Fidanza 8 pound (I think) in his Z6-powered EF hatch (now boosted). That's about all I've personally used on an ED/EF.
On my sister's car, a second gen Mazda MX6 V6, I put in a 9 pound Fidanza (down from a 28 pound stocker!) and a stage 2 Clutchmasters kit, I like that one too, but the V6 has a bit of torque and doesn't seem to have problems engaging. She learned stick on that clutch.
A few of my friend's have used centerforce and I haven't heard of anyone who didn't have complaints about them on many different cars, so I would stay clear of them.
