I've been reading about these lately as I have been using a BR curved shoulder strap for carrying my 600E. Info seems sparse on a net search, as well as over 6 years old. I've seen some comments here referring to failures, just curious if anyone has actually had a failure, and if so, what failed? Is this a real problem or just a few random occurances years ago that got blown out of proportion by the interweb. I'm carrying about $20k of lens and camera from one of these, and have permanently mounted the BR eyelet into a dovetail clamp with permanent locktite. The clamp then attaches to the lens foot as a tripod would.
