new to the boards. Would like to have a discussion about replacing the friction hitch with the petzl gri gri. Now I have done quite a bit of searching on the subject and realize the the gri gri was not made for arborist and there seem to be flaws that some treeclimbers are not willing to accept. Now with that said I just can't seem to get the darn thing off my mind. I keep finding new ways to use it and they seem to work very well for my experience. Today I used it in place of a friction hitch in a drt setup. After the gri gri the rope traveled through a micro pulley attached to a petzl ascender. So for my advancement up into the tree I was pulling down on the rope. I started with just pushing the ascender up with my hand and then pulling myself up a few tugs at a time. Next I began pushing the ascender up the line with a 21 ft. pole saw. Working hand over hand, I started to get up the tree rather quickly. The mechanical advantage allowed me to lift myself with a one handed pull on the rope. When I got to the top and wanted to start working, I simply took the ascender out of the equation, placed the micro pulley from the bottom of the ascender to the right side of my saddle and worked, cruised all around the tree, prunning. I even advanced the tie in point and felt really quick and secure while doing it. Now my question is why don't more people use this device for tree work. I read that the gri gri has a bad habit of slipping a few inches before it would cam. I have not experienced this. By the way I am using the 7/16 blaze and seem to have a really nice fit for the gri gri with this rope. Any input or advice would be great. Long winded I know but am looking for some learning experience that would allow me to keep the piece of climbing equipment out of my work bag.
