I can't believe what happened today. I went out to take a walk in a park hoping to see some birds, etc. I was using my D7000 gripped with the 70-200 VR II, as you saw from the last picture. I was also using an RS-7 strap, with the www.blackrapid.com/product/hardware/fastenr3/
screw attached to the tripod foot of my 70-200 VR II.
Before I went out, I made sure that the screw was tightened correctly and everything was secure.
But only 5 mins later, when I was walking, the "fastenr3" seemed to have unscrewed itself from the lens, and as a result, my 3 kg, $3800 worth of gear came crashing down from waist level onto hard concrete pavement..
I was in shock as I picked up my gear, the lens hood was smashed into 3 pieces, but nothing else seemed to have been damaged.. but my battery grip seemed to have suffered a few scratches.
I could not think of how it would have undone itself, and someone could blame me for user error, but I was 100% positive that the screw was attached properly and tightly.
As comfortable as it may be, I am having doubts using the Black Rapid strap.
