Over at TreeBuzz there are many threads showing the advantages of a self-advancing friction hitches; adjustable bridges; eye-eye cord bent ways I have never seen before. They all were just fuel for the fire for my investigation of \"Why Not!\".
Long time ago I set up a two CMI ascender system with the anchor point up over the limb and connected to the top ascender. As you climbed the down rope the up rope pull you up as well as advancing the top CMI ascender. Then I replaced the CMI with an USHBA and it runs like butter. A little pricey but heh titianum is a guys best friend.
The prusic minding pulley aka slack tender aka love me tender aka key chain biner can be used secured directly below the Blake's Hitch and thru an oval biner that holds the pulley tight and secures the up rope. You pull down and the system advances the Blake's Hitch with almost zero loss. Tickle the hitch to descend just as before. You will attach your saddle to the oval biner with a pre-tied loop runner made of hollow tubular webbing. Mine is 17\" long which places the Blake's Hitch at no higher than my nose. This \"smelling the Blake's Hitch is the prefect length so when you are climbing in a sitting position you can reach the Blake's Hitch to descend.
It is easy to change a loop runners length for every size climber to make the system tuned to every climbers size.
Instead of photograpghing an empty saddle I thought you all would get a chuckle out of seeing my Corgi's harness for tree climbing. Penny will come over on her own and stand on top of her harness when I lay it out. I guess if I had to chase her
around and wrestle with her to get it that might show her reluctance.
Here is Penny hanging around in the basement on a slushy Saturday:

Your harness is attached to the biner that is holding the micro-pulley just under your Blake's Hitch. The pulley is placed with its cheeks closed between two of the loops of a grith hitch. This makes the Bridge 2\" long and can be adjusted so it is always as high as you can go and still reach the top to descend.
