Interesting the arrow broke mid shaft. Typically the damage to a carbon arrow is at the point of impact. To break any carbon arrow at the mid point often requires a whipping type motion in combination with a weak spot (blemish, spot where another arrow has made a ding, etc...). I witness at least 350-700 shots per weekend of Victory products by all levels of archers. Based on the number of "stray shots" I have observe at the range over the years; I can honestly say Victory Archery produces a very durable product. I have met several folks at Victory Archery and they have always been helpful and take quality control very seriously. I would pick up the phone and talk with them about your experience.
