BHA is awesome. I've been a member for a while. Last night went to their party @TotalArcheryChallenge in Park City, UT. They and RMEF have partnered up or something. Pretty cool!
I used to have the Primos one until I got the My Sling a Ling. It's pretty cool that you don't have to take it off your bow because of the magnetic locks. jaktgear.com
I do. I've had mine for about a year now. The company is Jakt Gear, I think they used to be Bonewhacker. It's a pretty slick piece of equipment. At first I wasn't sure I wanted something hanging off my bow but it has this magnet system that locks the sling out of the way so you never even know...
