Doesn't happen often but it does happen once in a while.

It's a myth. I've had a 7lb Fidanza flywheel for over 3 years now. Everyone said "It's too light for daily driving, you're crazy, you'll lose so much torque." Besides nitrous, it's the best mod I've done as far as the engine goes.
Oh, and I've never had mine grind while trying to start.
