I ultimately standardized on Artisan & Artist Easy Slider straps (ACAM-E25R). I most often wear a strap sling-style, and these provide good adjustment possibilities for shooting and can "tighten up" the camera to the body when not shooting. These are excellent.
Before that I used A&A silk cord straps in the original length, which I finally decided were slightly too short. I was already invested in these when the longer length came out, and never tried those. I do miss being able to tie a knot in the right spot to create an instant wrist strap.
Before that I used, among other things, Domke Grippers (non-swivel version), which are great over one shoulder but too grippy to work well when worn sling style.
