Revs up quicker, but also revs drop quicker, both because of the less weight.

The issue 'some' people have is they complain, when casually changing gears, that the rpm's drop off too quickly before engaging in to the next gear because of less weight of a light flywheel, causing a jerk in car momentum, from getting the rpms back up again when in the next gear. Normally with a stock weighted flywheel, would maintain the rpms giving smooth engagement into the next gear. Its a comfort factor especially when cruising around town.
ahh yeah, i get it now.. Thanks for that.

to be honest, if that's the only draw back, i might as well chuck in a lightweight flywheel when next time i change my clutch (which should be soon - ive had it for awhile)
