Nice video. Gotta love those multi-topped bastards. My personal favorite grand fir growth habit is how they often have a dog leg in them, usually quite high in the tree. They have such heavy tops that you have to climb up past the dog leg and then rope the top above that. Scary and awkward to say the last. I will do most anything to get out of doing a grand fir removal. Nothing trashes your rope and flip line like those damn trees.
I am fortunate or unfortunate enough to live on a property with lots of grand firs on it. Last year I climbed up one by our cabin just for fun. I was about 100 feet up and was just enjoying the view. I made the mistake of pushing on one of those pitch pockets and it squirted me in the left eye. If I didn't happen to be legally blind in my right eye it wouldn't be that big of a deal. But with pitch burning my now glued shut left eye, I then I had to somewhat blindly set up my rappel, rap most of the way down the tree, pull the rope, and then rig a second rappel because the rope wasn't long enough for one rappel to the ground.
Then I was off to the cabin for an eye bath with olive oil to get the pitch out. Memorable to say the least.
