Ford has gone to aluminum driveshafts in many of their( if not all) cars/trucks, it was done to eliminate some vibrations ( I think it is called NVH,noise/vibration/harshness). So they are not totally without merit. It might be cheaper to get one of those and have it shortened. While it is true that you have to increase the wall thickness, I have had a few in my hands and they do represent a substantial weight savings that shouldn't be overlooked. Especially considering it is a rotating mass.
