This is not intended as a criticism of you nor your choices, but my knee-jerk response to such a closing is: best what?; but I suppose that in the modern world it is more appropriate than, say: "I remain, most sincerely, your very humble servant, Dumbledore." My response to that would be, "Yeah, right."
Okay, okay, I know what you mean, and it's fine. I just can't help being…me.
Upon reflection, I have to say that your closing, to my ear, has a greater ring of sincerity than the very similar "Best." That smacks of perfunctory obligation. Interesting, the little tricks our brains perform.
