Manual Transmission - Need Advise on New Clutch/Flywheel Setup!

Ok here it is, I have an '01 SS with 440HP and 440TQ and my stock clutch is not going to last much longer. I was leaning towards the Spec 3 and Flywheel Setup. It will hold the power and is resonably priced. I don't know whether to get an Aluminum or Billet Steel Flywheel? All advice is greatly appreciated...Thanks.

Do yourself a favor and get a LS7 clutch conversion kit (about $500) it will hold your hp and then some and drive like a stock clutch.

Textralia, pricey but everyone seems to think its a real nice piece.
