350Z Flywheels - Yes or No

Hi, I'm looking for a responce from anyone who is using a light Flywheel. I have a question for you, I have an 04 350z Performance edition. The car has been upgraded using the Complete APS exhaust and Turbo systems. The car is basically new with under 2000 miles. I know it's a matter of time before the stock clutch goes south and I have an ACT to replace it with. My problem is the Flywheel, is the extra noise and drivability issues worth the change? The stock Fly is a pretty trick peice and the weight is there for a purpose. What can I expect? Currently I'm making 320 at the rear according to a Mustang Dyno.
