You are totally wrong about the reason for a heavy flywheel. Sure you will gain torque when the motor is engaged . It takes less motor to spin less recipricating weight. But the reason for a heavier flywheel on a stick car is for enertia. When you have the motor at 3000 to 3500 for a launch it give the motor more spinning weight. Which take alot more to slow up. This gives the car a stronger launch. Also when shifting to the next gear it keeps the recipricating mass turning,
Now when it comes to accelerating in gear the light flywheel is the way to go. For an automatic you want a light converter. I use a 8 inch . Its in gear on the launch and it doesn't take as much torque to get it spinning.
On my 4spd car I use a heavy flywheel because I like letting the clutch fly and pulling gears at higher RPM's. The motor does not die on the gear change. The flywheel keeps the motor in it torque range.
On a car that you want to accelarate in gear with a stick car Lighter is better. One reason you don't use one on a sprint car . decelerate quicker going in and accelerate faster coming off.
I tried a light flywheel on a car with 456 gears with 10 inch slicks. I had to come off at 4500 and the motor would drop to 3000 on the launch. With the heavy flywheel I could launch at 3500 and it would just pull without droping off at all . It ould also not drop off in rpm's on the shifts. The Light flywheel I would have to start over on every shift.
So there is a purposefor either. But for every day driving heavy is better. It has nothing to do with your foot. It is just easier to drive. and alot easier on clutches. You can idle out rather then ride the clutch with more throttle.
this is not rocket science it is just common sense. If you don't see it .its your loss in competing with others who know better .
I only do what works and we are usually competetive. You won't change my mind with your B.S. I have been there in all types of Racing.
