What is everyone's opinion on lightweight flywheels?

I have a fidenza 8lb flywheel and no balance shafts, I've only ever had the car stall on me once just from pushing the clutch in and the car had a mis from bad plug wires so that certainly didnt help. Otherwise the only time I notice it is just around traffic driving that i have to make sure to keep the rpms up a bit more leaving from a stoplight when i'm slipping the clutch. Launching I cant really say if there is a huge difference because I have tires that just spin when I launch, a stutter box and my stock clutch wouldnt let me launch before because it slipped so bad.
