Is this an unrealistic fear? I've thought about fastening some sort of a "safety loop" attaching the regular camera strap lugs to the Black Rapid strap. Anybody consider doing that, or do you all have complete confidence that the Black Rapid lug won't work itself look while the camera is dangling from it?
I have an RS-4 for almost two months now and used it alot during a three week-trip to the US. I carried it with a backpack on dayhikes in Yosemite and the FastenR-3 never worked itself loose. However my friends 400D almost fell down because his normal Neckstrap somehow got loose.
Making me even more paranoid is the fact that I use a battery grip, so in my mind there are two possible points of failure: the lug that attaches to the strap and the connection between the battery grip and the camera.
The standart strap also has two points to fail
but since it is what everyone uses and hardly anyone has problems with it people trust it 100%.
My advice is to order the BlackRapid and trust it 99%. It won't work itself loose in a single day so if you controll it every evening you're fine - I found myself playing around with it when I was bored on buses. Screed it off screed it in --> tight again
