I have not had this happen with 5.0s but I did have it happen with a Bloodline (Easton). Brand new arrow, clean break, 4" back from tip, first shot into foam. I was told that Easton builds their arrows continuously and that when there is a pause/break in the process, there can be a weak spot (I interpreted this as a seam). The archery shop where I bought them, did replace the Bloodline. I like how Easton manufactures their arrows (as opposed to arrows that are built by wrapping around a mandrel which seems to produce a more pronounced spine). I shot hundreds of Eastons and only had this one out of the box failure. (I have lost of failures but, those were operator error.) I practice quite a bit and only turn my best arrows into hunting arrows so, for me anyway, I don't see this happening in a hunting situation. (I don't take virgin arrows hunting.) It is your call but, I'm not sure I would let one bad experience dictate your arrow choice unless you find another arrow that flies just as good (or better). Nothing this world is perfect. Just my 2-cents worth.
