I have the black rapid sport and find it great, apart from one thing. The camera swivels about on the carabiner and can be a bit annoying. I've just bought the peak design slide which is much better in this regards, but it's not quite as comfortable as the black rapid on the shoulder. Not at all bad though and still comfortable, just the BR is very very comfortable. I am going to stick with the peak design for a while though and see how I get on as the lack of camera movement is a great plus, as is the release mechanism.
