Honestly, it can hardly be disputed BUT:

Number 9: I don't feel carbons are easier to "roll your own" compared to aluminum....in reverse, sometimes carbon takes slightly more care when perparing them. Epoxy vs hot glue on some inserts, cutting, splintering, sanding etc...aluminum is slightly easier to build your own in my opinion and I've done hundreds of each.


And to mention your own response, by the time you shoot the spine out of a carbon arrow, you've probably already bent or creased an aluminum of the same usage.
