I opted for this for my camera's, it allows interchangeability of strap, depending on camera being used. Additionally, it a short lenghth on camera, so when you want to use tripod or store away in case its not combersome with a long strap.

Also a xtra large extension strap, this allows you to carry on sholder and strap across chess and hang at waist.
I 'll give this a go, and see if I fill comfortable with all aspects of the set up, I can always move to
caribiner & swivel hooks.
I seen the caribiner & swivel hooks, but wasn't sure if it would rub on body damaging it, because of the metal connectors. What has been your experience.
