I cut a dozen of the new n'fused ST Epics today for my dad. I squared them up and put the inserts in this evening. I spun them with broadheads too. The inserts went in very square and they pretty much all spun true. The vanes should be here tomorrow so I can fletch them and get them in the mail Monday. I'm really impressed with the quality of these shafts. For the distances he shoots they ought to serve him very well.
