I agree, no reason to replace arrows unless you're not satisfied with what you have for some reason. I replace them if they get busted, RH'd, I striped on a couple weeks ago, shooting at 24, 32, 40yds, I dropped and arrow in and it sounded "different, but when I got to the target, they weren't as tight as I thought. Well, I go back to shooting, and as I draw, I realize what the sound was, I'd hit the arrow in the side of the shaft, and busted the shaft and weakened it enough that fibers of it started to separate as I drew the bow.
