I personally think the real value in a aluminum drive shaft isn't so much the fact that it is lighter, so it accelerates quicker using less effort. But that it allows more torsional twist. I used to know the hard numbers I got from the Drive Shaft Shop, but I have since forgot them since I didn't wright them down. But I want to say there aluminum shafts (mind you this was on a different car entirely) allowed several times more twist. Something like steel I want to say was 3% and Aluminum was 14%, or maybe it was 7% and CF was 14%.
Anyway the point being that this additional twist helps reduce the initial shock of a hard launch on the rear diff. Which = more reliable, with the addition of a little freed up energy under acceleration.
