I got one on these, the Rapid Strap. I'll never go back to a conventional strap.
DW carries the Nikon D300 with wide angle lens using the Nikon strap. I went with the Rapid Strap cuz I carry the D200 with the zoom lens. I will never use anything other than this strap. Have gone on many trips and many hikes with this set up. The most difficult was the 3 days we spent walking Arlington National Cemetery and all the rest of the sights in D.C. Weather was in the mid to high 80's and I was not bothered at all by carry my camera with me all day.
