Lightweight flywheel...streetable?
My clutch is fried to a crisp (had to get towed back to my apartment 
). It was pretty much on its way out the door anyways. While im replacing the clutch assembly i figured that i might as well upgrade the flywheel to a lightweight unit. I've been looking a lot at a Fidanza unit rated at 12.5 lbs. I was discussing this option with one of my teachers and he mentioned that, while improving acceleration performance, it could hamper driveablility. He went on to discuss that the computer would have trouble compensating for the quicker revs and could studder a little as it went through the RPM range 
kinda iffy on this issue. Also he went on to mention that while RPMs rise quickly, they would also fall more quickly as well. This i can agree with and could understand that it could be uncomfortable under engine braking, but could be dealt with by just pushing the clutch pedal.
Does anyone who is running a lightweight flywheel have any of these issues, are they a bother, and would you recommend one as an upgrade? Also any particular brand that you've used and could comment on? Any opinions would be appreciated.

I had the fidanza and loved it. Engine response is GREATLY improved. Yes the revs rise and drop quickly which is exactly why I installed it. Shifting must be done quicker in order to match the rpm's. Lazy shifting is not allowed. Rev-matching is now fun as well as heel-toe downshifting. Engine braking is also improved. The ecu will not be affected. I highly recommend this upgrade only for the SPIRITED driver.
