Ughhhh I gave up on finding a perfect all in one solution that didn't have too many drawbacks. I just use a BR RS-7 and keep both a monopod and tripod plate each in each my two bags. I switch from film to digital bodies quite often and like having one strap to use on both, The Black rapid sling does a good job. I have a Carry Strap BR clone but it just doesn't stay put and the carabiner thingee loosens up over time. It just stays at home now.
