Very nice! I especially enjoyed some very interesting and beautiful "global" uniqueness arguments to get going! :^)

I think that just might be the one puzzle I'd been dreaming of with all my symmetrical creations haha -- that is just amazing
I'm kind of split on how I solved it though, but you did have that one 'fact': after goodliffing a bunch of X'd cells, I stared at the grid for like 10-15 min, then wrote a bunch of digits straight away (I'm sure you know exactly how many), cleaned the pencilmarks with those and went on. Fastest I ever solved a 5 stars, but if I had to give detailed explanations, it'd have been pretty fuzzy!...
