i noticed today while shooting that my string loop is getting really frazeled..well my release got hung up and i made a bad shot.. well i figured its the way i clipped the loop.. the next one i clipped on my loop and pulled it about half way back and it came loose and my arrow went flying (I live in a residential area) so i hope it didnt hurt anything.. needless to say i cant find my arrow. so i am going to have to restring the loop.. how may shots do you wait before you change??
