I shoot 33" 2315' s outta my round wheel compound at 60 pounds. I always spin them in the palm of my hand after shooting them, but after all these years it' s force of habit. I even do it with carbons. Maybe once in every 200-300 shots I' ve pick up a touch of wobble that' s easily tweaked out with the arrow straightener.

I won' t go any thinner than .015 wall thickness though. That' s the absolute bottom edge of the durability I find acceptable.

Also, I agree about the 2216. Those bad boys will shoot off just about anything, probably the most versatile size aluminum Easton makes.
