I didnt really know a good title for this, but came across exploded carbon arrows stuck in peoples hands... Well needless to say Ill be flexing mine alot more before I shoot. Also I shoot at some things I shouldnt, and recover arrows in the ground, small wood or my fence. Mostly shooting easton epic's st n fused (340's) and I have some gold tip hunters (rated at 400) I shoot at squirrels. Is there a rule of thumb for arrow replacement time. Im sure these arrows are spined fine for a 58# draw. Also saw some videos on people derailing their bow strings.. not letting anyone "see" my bow anymore after that video, first thing everyone does is yank your string back by hand.
