Whats the advantage? Why not use a single eye pulley? That seems to waste the function of a hitch climber. You've essentially rendered the other termination eyes of the HC ineffective because it can no longer be considered life support due to the dogsnap.
Id take that back to the drawing board!

Let me try to explain how the "drawing board" got me to this point in the lanyard. I'm really liking it by the way.
Once I ascend into the tree I use two lanyards for working my way up thru the limbs. The HC pulley simply tends the slack on my lanyard and in this configuration I find that it does so with great efficiency. Because the snap puts the pulley in just the right place to capture almost 100% of my rope pull.
When I used a pinto type pulley on the carabiner, I would pull up say 8" and settle back down on just 4" of it. Meanwhile the HC pulley was just being carried or left on the tail of my climbing line.
So now with this setup, when I am ready to leave the lanyard and continue with the climbing line, I just take the HC pulley off the snap, leaving the hitch and carabiner in place, then I put the HC pulley on my climbing line where I have the hitch and carabiner, and use the HC pulley in whatever configuration is needed such as the "V rig" or "M rig" or all those other multifunction uses that I am learning about.
Also, for me, on the lanyard, I have found that the Michoacàn hitch is the smoothest and surest and most compact.
Another note, in this configuration, I don't think the snap is really part of the life support function, only tends slack on the lanyard so the integrity and life support of the lanyard, the e2e and carabiner are intact.
I hope that makes sense and I really appreciate the input. It is a learning process and a progression that I am sure is ever changing and what works for one may not work for another but only by seeing and learning from others am I able to move forward.
Thanks
