Congrats on a safe adventure. The most important thing about running a saw aloft, is the double tie in. Always have your lanyard on when cutting. Up on a 5" spar, it is easy to gaff out and slip, if ya only have your TIP on, and it has weight, one little nick and your down in the blink of a eye. Never make a cut unless you are comfy. I have yet to try Gecko's, but I freaking hate spikes in general and will climb with out them when ever I can. Normally,the only time I have too is when removing a lion tailed silver maple, one that has a clump of leaders with no structure. Even on rough bark trees I go without spike as I have something to get a grip, those silvers are so freaking slippery, add in lichens and some moisture..... Sometimes, if it is a bad one. I will have my TIP in and then shoot a line into the top of the leader I am removing, then hip thrust up on that one, then pull slack on my TIP. Using a the second as a lanyard. I do all this to avoid spikes, they hurt me that much. I have to get them so tight that I have to have help getting the buckles in the last holes. I am a pretty small guy, 5'8" 135-140lbs. I have adjusted them to every possible configuration, no luck. I have thought about those ones that have the shoe bottom's and adding the Velcro. Anyone ever had those? Thinking about having gaffs grafted to my ankles, then I can just screw them on and off when I need them, like those dudes with spikes in there heads! All I know is spikes suck! Why I want the Goth mod.
