One thing I didn't like about both your pic Ox and the wes spur cover is that you both have "saw in hand" as the piece is falling into the rigging. If you set up your hinge well, its fairly easy to set the saw on your saddle, so you can be ready to brace yourself with both hands. You know there is going to be a little (at best) ride coming. I guess on a front leaner some will just keep cutting til it goes, but I don't see the need or sense in that. I;ve seen guys that do a lot of rigging down a spar, just drop their saws onto a long lanyard, which seems very effective, especially for those situations where a quick transition is required.
Also on the cover shot, as mentioned it seems like he is mighty low relative to the cut, and the hinge looks questionable.. as far as the lanyard placement, I like to tuck mine up right under the sling, so there is no way the block is going to touch it. Keep the climbing line below as well, usually well below the low point the block can reach.. rarely if ever work off a choked climbing line, but will use a FS tucked under the sling. I usually set the sling before I make my cut, and cut down pretty close to the sling, so I don't want my life lines anywhere near the cut..
