When you have a chance to look on youtube or google videos, type in death grip hitch. I found the smallest diameter pole object that I could find ( 9 or 10mm rail for my sons safety gate). I tied a 5 wrap down and 6 wrap up on it and had no movement. I had to stop putting weight on it when the whole gate started to want to come out of the wall I have it bolted into. I used a 8mm cord. Again I dont expect you to use this hitch for your training day, but this is something worth looking into when you have a chance to play around. It just hasnt slipped on me yet. Also good point to make out on the physics of this hitch, the way it works on its self under a load is to chocke in two diffrent dirrections with the wraps and then the load end pinches down on the whole thing. For this rescue set up you will not find a better hitch.
Ok, so that is about as much " obsessing" as you will ever see me do!

I'm diggin' the over engineering. ONe thing to possibly change is u-channels on both ends may be a little more secure than the set up you described other than that good idea.
You have me intrigued with this hitch. I'll be playing with it next week on my dayworks.John D. Calamia, BS, NREMTP, FP-C

Mike, this is the type of crane stuff we are talking about?
Noticed on firespecialops dot com they had an exterior rescue on one in long beach... http://firespecialops.com/2010/11/03...-2-from-crane/
I know it is not what we are talking about, but I am bored working on Christmas.
