Light weight flywheel - good idea?

I have a FMS 351W crate motor that is rated at approximately 425hp. The doc says it has a steel billet flywheel. My ERA Cobra has 3:31 rear gears and a Tremec 5 speed. When I switch to the Tremec TKO600 RR (2.87 first and .82 fifth gear), I want to consider changing to a lighter weight flywheel for quicker engine revs but do not want to lose much "street manners" especially pulling away from a stop.

Anyone know what the weight is on an FMS steel billet flywheel? The engine was assembled in 1995 / 1996. Some performance flywheels are steel or alumimum, some weigh as little as 15 lbs. Are these light weight flywheels a good selection for spirited street driving? I would like to see quicker revs.
