I have recently appreciated the positives about aluminums.

1.) Easy to remove/repair inserts, using good adhesives like ferriletite
2.) Easy for anyone to cut and get square ends without 8billion RPM motor
3.) Fletching alums is a breeze with most glues.
4.) Almost always straighter/more consistent spines
5.) nice and heavier generally than carbons.
6.) just plain gets the job done, if you coudln't get it done with alums, then carbons are not going to help you.
