mahk adams does an interesting article on this particular hitch and gives tieing instruction and origin under the articles section on the buzz site
i just started climbing on this hitch, it worked really well on my ocean polyester cordage that was 10mm against my poison ivy line that is 11.7mm, the vt knot would not allow the op line to sinch up, the michoacan knot worked very well
today i tried this knot using an ice eye to eye cordage and it wouldnt sinch, nor would my vt knot, and its an 8mm line, im guessing it has something to do with the materials, i guess im stuck using beeline from here on in
happy climbing brother
