im with jeff g on this one. a four inch loop can slap you silly, plus breakage etc. i dont know for certain, but id also think with that long a loop you would tend to pull away from straight back as a short loop you only have enough leash to pivot. if that long a loop ever broke or came undone from the string...you could take a chunk of skin off your face and we could hope it aint your eye as it whips through your release.
