Have the Black Diamond. I like it, but do have a couple points I am hung up on; has two pockets, one is useless, the other is almost useful. Also, while the while the SQ Balance has a strap that comes in fastens across the front of your body, the Black Diamond has a rather intrusive cumberbund (Sp?) with a uselss little pocket, making it even more intrusive. I have learned to live around it, but next BC will be something different (like a zeagle), or BP and wings....
