Of course nothing is perfect. I have yet to meet a handyman who can do a smooth even caulking job, and this was no exception. The Affordable (and corner-cutting) Plumber could, but he didn't caulk the whole thing, is why I had to get someone else to do it. Also: should have supervised the baffling job, because if they'd put the first baffles higher they wouldn't have needed to add two more. But on the whole, very content.
Also: Bakka does indeed have Aliette de Bodard, in a door-stopping compendium of all three volumes. Am still thinking about this, because that's not a book that will travel at all.
