oops! My bad. I didn't read your post carefully.As neuroanatomist mentioned, if you use tripod often, BR is not good for you.
I don't think I mentioned that. Personally, I have the BlackRapid FastenR-3 semi-permanently attached (with a little Loctite Blue) to a Kirk QRC-1 1" clamp, and I have Wimberley Arca-Swiss-type plates on bodies, and on lenses with tripod collars. That makes it very easy to switch the attachment point of the BR strap, or remove it and mount the camera/lens on a tripod or monopod (both of which have a Wimberley C-12 clamp).
I do have problem to use the BR with tripod because of the edge of the BR mount. By the way, after I use the BR on my 5D2+Grip+24-70mm for an year, the mount of BR shape has changed a bit.
