I use reparrows for those arrows I break an inch or two behind the point, wouldn't think of putting one in mid shaft.
I draw 25" and cut my arrows to 28" BOP for the best flight out of my selfbow.
I go all out on arrow construction, tapered, crown stained, intricately crested with wild turkey feather fletching. I would hate to trash one of my extra special arrows just because it is missing a few inches on the front.
A reparrow let me keep the arrow in my quiver. With a little adjusting you can get a perfect mating of shaft and repair point.
You may break the same arrow again in the future,(dang those boulders behind 3D targets) but it has been my experience that it will never break in the glue joint or reparrow portion, always somewhere in the formally undamaged shaft behind the repair.
