I am not a ..."fan" lol...of that internet branch, since it was found, and your best developed branch is far superior, I feel like you may not like it that much either.
So I don't want to just talk smack about that branch, but I will because it is also, in direct opposition of your goals...goals which I love and respect BTW.
The best goal is viewing that "represented as good" tree from the NC A and identifying it's flaws. That's an impressive piece of humanism, not wanting your tree like that "popular" one. Respect!
I find that internet branch so poor and in conflict with your goal, because it seems either, wired as was to make a "branch", or grown absolutely piss poorly from scratch, at least IMO. Quite the same as those NC A tree's branches were grown. This is "OK", but you do have an opportunity to make yours much better.
I believe it is important to have this understanding, that, a 8/10 tree can be made with what IS, but starting from scratch with patience and determination can make 10/10's.
Ain't that about a branch!
It'll make sense to conclude this bit on branch structure with what my idea of a perfect branch structure is, it came from that RNeil video, the part about having a "backfill" branch before your fork. Since 2, 4, 8, 16 forking is mostly 2D, that backfill branch became key to me...
When dragging branches down for a conifer, keeping one top bud before your forks or "proper nexts" to repeat the pattern of one top bud and 2 forks.
The green your regular "proper nexts", with the yellow the fill branch.
This pattern can be reversed for D's with upward sweeping branches, keeping bottom buds for fill.
It can be altered by 90degrees to fill space, this "fill space" being something a tree does naturally.
But most importantly....
MOST IMPORTANTLY!
After 10-50years or so, when branching has run it's course, you can cut all the way back to that first top fill bud and bring the whole thing back into closer shape. Long game long game.
When your first fork is left or right, it becomes much more difficult to bring a tree evenly back into a close shape, it leaves a better chance of having "naked spots".
This is "100 year think", not many folks in that zone, but I find the farther out your plan gets, the nicer and quicker things to come together for today.
It's kind of a mind trick. As soon as you accept the super long game "patience" just happens.
Where as....wanting to get a tree "finished", leads to eh ...flaws like that NC A tree has.
Well that was a long conclusion.
But this seems like stuff that lines up with your goals and attitude towards this material and endeavor in general.
I may like that more even than I like this tree, because that is going to make this tree so good!
On to "how to get there", of there is one, with pruning. But it ain't just pruning! (And likely not pinching!)
