Flywheel choice steel or aluminum?

Which is better setup for a street driven car a billet steel or aluminum flywheel? I currently have an aluminum setup with a Mcleod twin disc, but I was wondering if I'm leaving a bunch on the table in regards to spool up time.

I've always used steel, aluminum is less weight, but doesn't have the momentum/rotating mass like a steel one does that can be helpful when you get into the next gear or I would think would also help load the turbo some too.

87 GT 306 machined/built by me..Windsor Jr heads, E cam, GT40, lt's, Tremec 3550 etc....Tweecer R/T tuned PLX wideband

Bunch of parts for sale..306, fully forged 347, 0 mile 357, Fully Forged 408, tremec trans, clutch, and more....

There is nothing wrong with light rociprocating parts. The less inertia the rociprocating assembly has the less likely it is to break tranny parts... If you had an engine that made very little torque a heavy flywheel can help. Think about that rotary that you see at the the dragstrip.They leave on a flywheel and are out of power by the 330', but still et well. I don't even think the guys in Pure Street are using heavy flywheels and they make peak torque around 6k...
