Thanks!I've used BR straps for over a decade, and been very happy with them. It's 'rapid' because the camera attachment slides along the strap, instead of the strap sliding around your body. That means that 1) the strap can have a padded section that remains in place (more comfortable than the unpadded RRS strap or the Kirk strap that I tried), and 2) the strap can be worn and used with a backpack in place, because the only part that's moving is the camera.
I had a BR strap years ago, but had a camera come totally loose more than a few times. I would check my BR connections regularly especially during long hikes but occasionally they would loosen up. Because of this, I now just hold it from the lens foot. Maybe its time to look at the BR straps again.
