Egigik and Nushagak don't count as beaches when the sockeye are running....more like international airports...
DC-3s, C-46s, DC-4s, DC-6s, and at least one DC-7. Quite a show, actually. Those beaches are really solid, in any case.
That said, I pretty much agree with your points, except if you're going to wheel land on a place you haven't landed recently, do it tail low.
