I definitely assume you're way underspined with 2212's. But that's almost beside the point... Why even mess with aluminums that light?

If you're getting 2212's to fly at all, then you must have a relatively short draw length. Going on the assumption that you need different arrows, I'd make this suggestion. Get some good quality carbons, not the cheap junk. Have the shop cut them to length, taking half off each end so you'll be left with the best, straightest part in the middle of the shaft.

The carbons might not be as perfectly consistent as the 2212's, but they'll be good enough. They'll definitely be a much more durable arrow. If your 2212's are bent - and if they're as underspined as they sound like, then they probably are - you'll get much better accuracy as well as easier tuning.
