Hey Ben,
I assume you gutted that hinge on purpose, so that wasn't an unintentional dutchman that blew the center and left side of that hinge.. If so, good job.. if not you suck LOL.. hey, you guys asked for my two cents, so don't blame me..
Seriously though, that's A LOT of climbing and cutting.. and material to handle with a mini afterwards.. Good JOB! I don't have the patience or stamina for that kind of climbing. I can't even stand to watch a slow climber do a big nasty take down like that, and personally haven't climbed a monster tree since 2010... I did just take out a monster horizontal Norway maple limb from the saddle this week... Over 40' long and 26" at the cut. I haven't seen the video yet, but I'd guess the cut took somewhere near 40-50 seconds.. That I have the patience for!
