ive used a blackhawk single point for 3 years now... one of which was in iraq, personally i feel theres no better way to sling an ar15. now if you have a rifle and not a carbine, then id go with something different. as far as bouncing around, i dont have to much of an issue with that since im either at the "low ready" when im outside the wire or have my hand on the pistol grip while walking around the fob.
