I still prefer the Op-Tech sling kit with the utility strap. Cheap, simple, functional, comfortable, and without holding up the tripod socket like the Krap-Rapid (yes, some of us use a tripod often).
With the quick release buckles, I can pop off the strap in seconds whether the strap stays on and the camera in hand or if on tripod and the strap isn't needed (windy days to reduce wind-induced vibration).
The other nice thing is that I can use different Op-tech straps with it by clipping it into the buckle system (lightweight strap, wrist strap, etc).
This is how I have the straps configured on all the 1-series bodies - right top strap loop to the bottom-side strap loop so that the camera hangs sideways. I can reach back, grab the camera and the strap stays out of my way. I have the RRS L-bracket mounted on the left/bottom side and I can slide the camera on the tripod without the strap crossing on top of things.
