I second the Legacy 2016s. Aluminum is easier to work with. Like using heat to turn/remove your inserts so your broadheads will line up the same on all of them. And you don't have to worry about scraping old fletching off of aluminum shafts and damaging them. Carbons will crack on the point end too. Aluminums, generally, are cheaper, too. But, I know if they get a dent/ding in them, then they are done. I've shot both, but only aluminum in trad. Still, I prefer aluminum for the above reasons.
P.S. Let me know if ya wanna trade off those 2016s. I may have something you need, who knows?
