That was all business as usual for trees that size in that setting.
Not much room to put them down and not much crown weight to pull them trough.
In that case you want as little hinge wood as possible.
He also followed the faller's 1st rule: if at all possible, fell them towards the lean.
That way you can set a tree that size on two stamp size pieces of hinge wood, just enough to get it stated towards the lay when you trip it.
Then it is free to roll and slide left and right as necessary and it get a good initial speed.
Only thing that irritated me, was he didn't clean up his escape route.
If you know you have to get away fast, clear your route.
My apprentices know, when I start cutting saplings down and removing branches from the ground, that some heavy shit is about to go down.
Of course, if everything goes wrong, you may have to run another way entirely.
Burnham once posted a video of him taking out a huge, rotten Doug fir.
Had a nice escape route planned out and cleanet up.
Then as the tree goes, the top 3rd or so broke clean off and came backwards, right at the eascape route.
Burnham, being an experienced faller, had an eye up, of course and changed course, running downhill like a rabbit, gimpy hip and all.
The mushbag of a top landed right where he would have been, if he'd followed his original plan, exploding in a red cloud of dust.
One of the best videos I've seen.
Some of you may remember this one:
One top broke off and came back. We were locked in by a ditch on one side and a felled tree on the other,
so could only escape directly backwards, which is where it was going.
That was a "Run, Forest, run!!!!! moment.
