It is interesting to note what a different arrow Mr. Cousins shoots at the indoor archery bronze medal tournaments compared to the outdoor tournaments. The arrow has a much thicker shaft, and much larger fletchings.

When shooting indoors, the archer is not worried about how much the arrow slows down over the shorter shot, and they like the thicker shafted arrows to help break the lines of the higher ring.

Outdoors, over the longer distances you have to worry about wind, and how much the arrow flight is slowed down by the fletchings.
