Not sure if the author is reading these comments but if you like the Moonlander but don’t like how the thumb cluster is tied to the tenting angle, I strongly recommend their ZSA tenting solution. It makes the whole thing a lot sturdier but more importantly it lets you adjust the tenting angle independently from the thumb cluster angle. You can also probably find used ones online.
I know you mention it already in the article but it is really worth trying out. You even get more tenting angles that would previously be impossible without it. And it just makes the whole thing a lot sturdier.
