I'd normally go for T19 for date subs, T39 for no-date and SDs. They are high, but on very sporty vintage divers, so I like em. Rem that a superdome is intended for underwater enhanced redability, some sort of big cyclops, they are awesome for that.
+1 on tropical gens, they obviously look a lot nicer, given the fact that they are pricey. If you can live with it, Clarks are good stuff, there is another dealer called Taka E-mart who has very good ones, shipping from Singapore if I rem well, 25-35 bucks or so, I'd give it a look.
Interesting watch Freddy.
