This looks like what I'm interested in, I think. Do you leave it connected that way all the way up the tree, while hunting, and all the way back down, or is that just for the rappel back down? I suspect it's just for the way down, since i would think the autoblock gets unwieldy during the ascent and while hunting.
So when you're at height and on a platform/ROS, you switch to the amsteel bridge plus a ropeman and carabiner?
I was wondering if a single device could be used in all phases. Like an amsteel bridge, carabiner, plus Sterling ATS, or ATC, or Rock Exotica Mini 8 - long as there was a reliable lock involved that could be trusted. I'm worried about when there's slack (like you've just climbed up your stick and need to move your tether up) or you're standing on your platform, etc. I wouldn't want the rope setup to move/slide... but I would want it reasonably easy to switch into rappel operation for when it's time to come down, fingers are cold/wet, gotta stop and undo platform & stick, etc.
Sorry for repeating some questions here, or asking dumb ones. The concept is really capturing my attention to save weight.
