Another very nice puzzle! As you know, I'm a big fan of quadruple/inclusion sudoku and I would definitely love to see more of this variant out there because there are so many set-ups to be had that would make for enjoyable solve paths. I've never seen a set-up where there were a few quad clues and then the rest were bivalue inclusion clues; I like it a lot :)
