Aluminum Flywheel
I was wondering if anyone who had a steel flywheel and changed to an aluminum one noticed a difference in drivability? Example: Is it harder to start out from a dead stop because the flywheel is lighter?

Not harder just different. You have plenty of torque to get the car moving. It took me about 10 minutes to get used to it. Now I don't even notice it taking off. It does rev much quicker. Highly recomend a lighter flywheel.

A lighter flywheel will give you the lopey idle we like with a milder camshaft. To save money, you can always have a steel flywheel machined to be lighter rather than buying aluminum. If you're really cheap like me, you can drill a bunch of 3/8" - 1/2" holes in it to remove material, and then balance it out on a wheel balancer, drilling holes on the heavy end. Those machines can get it down to 5gr imbalance.

Lighter is almost always better when it comes to rotating mass. I had a Fidanza aluminum flywheel and really didn't like it. Yes, it requires you to slip the clutch a little more carefully. After I sold the car, the new owner told me that he stalled it 6 times just trying to get it in his garage! 
Next time I'll buy something a little bit heavier, like a light weight steel flywheel.
