What is everyone's opinion on lightweight flywheels?

[A//// Guy]

Wow I didnt know this many people had lightened flywheels. Is it really worth the few extra horses? Sure there are a few gained but is the price justifyable? Just curious if anyone has a dyno camparison. I would only thing between shifts keeping the rpms up would help, but if you have NLTS then theres no gain.

I agree that less weight = more power, especially rotating weight but Im curious as to how much is gained and what are the disadvantages of just runing a stock flywheel?
