Yeah, it's a weird thing amongst tree-guys. My foreman and I were just talking about this, this morning. 90% of all tree-guys have heads that are so big, and so hard, that we have a super hard time admitting that the guys who do stuff different from us cld ever be right.
As to your Elm hinge. (We're friends now right?)
No man, I mean, the bottom line is you dead-centered your lay, and my hat's off to ya, and let me preface this by saying that I am a card-carrying Wanna-Be Faller type and by no means have even come close to earning the rank of considering myself amongst the faller types.
Here is what I think the PNW "Faller Types" wld say. "You completely cut-off yer far-corner!" O.k. back to me again. You explained in your video that you made a deep undercut to shift the center of gravity toward the lay, but how cld this matter since you have a pull-rope? The benefit of having a deep undercut wld merely be to extend the LENGTH of hingewood slightly. But you inadvertently negated this advantage by totally severing your compression corner, thereby "stacking-up" far too much compression on the middle of your hinge while incidentally compounding unnecessary tension on your tension side. Does that make any sense? I believe that all of this comes from over-rating the minimal gains of a "staggered-hinge" during the cutting process. Yes, the higher corner on the tension side will help some. Yes the increased width of holding-wood on the tension side will help some. But, in my humble opinion, any advantages that you wld have gained having implemented these techniques were greatly minimized do to your inadvertent severing of valuable compression-distribution surface on your "far-corner."
Make any sense at all? Still... you da man. O.k? Hit your lay. Bottom line. Well-done. O.K? Friends still? Hey man, look at how long this post is. I obviously need a friend right now eh? Jay's cutting me off for drinking too much.
Jay: How'd you know? Was it all the red-neck jargon in my last post to Murph?
