Ordered the RS-7 and Fasten R-T1 today. I'm still not certain how well it will go with my Really Right Stuff camera and lens plates as they're a much lower profile than the Manfrotto quick release plates. Will see anyway - it looks like a really good solution for carrying the camera around, just a little bit more work when attaching to a tripod if I need to remove the strap.

I'll let you know anyway, not sure who else here using Really Right Stuff plates, I can't really recall anybody else.
