Question+Review: Black Rapid RS-Sport
Regarding the Carry Speed Strap, here's an interesting read...........
I've owned a couple of the earlier versions of the Black Rapid straps and got rid of them due to variations in the mounting ring. I chose the Op/Tech sling which attaches to the camera's strap lug and easily integrates with their quick release system seamlessly. The sling and the rest of the accessories cost about 1/2 of what the BR sling cost.......
My bodies all use the Arca Swiss L-plates which I leave attached all of the time so the strap lugs seem to be a better overall mounting point.
