HACK
What I was going to say I learned is, after cutting multiple hickories they will hold and spin with as little as you pinky being the problem, second of all you notch needs the top at about 45 degrees and the bottom at negative twenty or more. Talked to a logger friend he said they consider them death trees when small like we cut. He said the are never predictable. Any way thats my two cents for what it's worth.
Yes... Make the face cut large enough to get the tree to the ground... Some woods are tough... Strong enough that an inch of strap can hold them in suspension... That's bad news... I think your thinking here is on the right track.
I had a very large Elm sit on its notch... Huge pain in the ass and tense situation getting it to the ground...
An anemic face cut was the problem... Use a notch sufficient to get the trunk to the ground without closing it's mouth.
Learned my lesson...
