I have been a Q Strap user for quite some time but after nearly losing a lens over the weekend I was tempted to move over to the BR system.
However, I looked around and have just bought myself an Op tech sling strap. I like the fact it is modular and using this I can now have two points attached when dangling my D700 and 70-200. One connector to the lens, the other to the camera body. Just gives me that safe feeling that I have a 'backup'.
Not that the connector should snap. Last night I suspended 3x the weight of my camera combination from the connector and shook it. It held comfortably. The rated max weight is actually 60+kg.
LOL reading this, i'm tempted just to do a review in the right section. But just thought it might be another option to consider given it is much cheaper than the BR strap.
