Frans- how'd that thing work out for you. I made one last week that was identical to the one I made you....and I like it. I've done a few trees with it and purposely descended super quick out of them. The technora looks dirty, but not damaged.
I had to play around with the hitch a little to make it work. I was first using a 4/3 VT, but that wasn't grabbing sometimes, so I switched to a 4/3 XT and that seems to be working much better.
