If all you're doing is shooting, and you're not sharing a camera, then I imagine the BlackRapid strap is wonderful. While I liked the initial feel of getting the weight off my neck, but, after a week or two it was taken off... either the strap was in the way, or it put the camera/lens dangling in the way, far, far too often.

We often share a camera, and we found that the strap made that extra annoying. Shooting without the strap in use is extra annoying too, as it's not as easily held up and out of the way as the neck strap. It's also annoying if you're doing anything non-photo related. The camera hangs lower, and swings around, when not in use, which means we need to be extra careful when bending or squatting down. ie: to tie a shoe, going to pet one of our dogs, giving them a treat, or picking up after them. We need to take the camera off and find somewhere for it to sit temporarily when helping to move anything.
