I've never trusted quick release thingies holding my camera (if they can, they will), which rules out OpTech and many other straps of that type. For years I have been using Domke straps without the metal swivels (I also don't like anything metal close to my camera... if it can hit a lens, it will... which has kept me from using the otherwise remarkable original Domke bags: flying metal fasteners). The woven-in rubber strips on the strap have always worked well for me, even on slick nylon jackets, the strap is very flexible, comfortable on my neck and, if need be, wraps easily around my wrist when I want to carry the camera that way.
