Just to add to the thoughts, I use a double rapid strap for two body/lens combos and while you can use each strap individually, they are cumbersome for me so I recently started using something else. I have a shoulder strap from a fairly expensive [when new] piece of luggage. The strap attaches with the carabinier style clips, the sort you have to slide backwards and the then press in, and they are pretty good quality too, its takes some effort to actually slide then press [as in, unlikely to release accidently] I only used this when using one camera, just for short shoots outdoors or the hobby stuff [so not in the middle of a wedding] and it attaches to the normal hooks on each side of the body and of course, can be removed quickly and easily [unlike a normal neck strap]. It also has a whopping great shoulder pad so is comfortable to carry either over shoulder or diagonally across the body.
So, here is my question, are any of the strap makers doing anything similar? A neck strap [so the camera is carried upright] but with proper quick release but secure clip fasteners? yes I know some of the optech type straps have the removable bit and you can clip the 2 ends together to make a very short strap, but I want a fully removable one. :shrug:
