I love this argument. It has been going on for years and will continue to go on probably long after I am gone.

I shamelessly admit shooting mid-priced carbons...both Beman ICS Hunters and Easton Carbon Excels. I feel that I get very good accuracy out of both arrows and have found them to be extremely durable.
As for the issue of spine, weight and straightness consistancy...what can I say? I think they have improved in recent years but will agree that they still aren't quite at the level of aluminums. I will say though that, eventually, they will catch up and then I would be interested to see what type of arguments many of the die-hard aluminum guys can come up with.
