I've used both the Easton Axis Nano and the CX Maxima and Aramid KV. I can definitely say that I'm not real keen on the slim tech internal insert on the Axis shafts. They tend to make the end of the shaft shatter on a heavy impact (both on the FMJ, A/C Superslim and Axis Nano) and you can't ever get them out again once they're glued in. I'd lean toward the CX shafts and if you can afford them (and don't lose arrows) I've been real impressed with the durability of the Aramid KV's.
