For your application, alum or steel flywheel will feel about the same. In racing, the light weight whel will rev up quicker, and drop down quicker, and that can be a benifit. They drive about the same.

I use a Centeforce Dual Friction 10.5" clutch and pressure plate. Very smooth off and on. No chatter. easy to modulate. moderate pedal effort with a cable. Durable, too. I can get about 3-4 seasons out a clutch.
