Hey Jeff,
I've smoked plenty of striped bass. True, it is a drier fish, but flavor brining and careful attention to internal temps are well worth the effort.
I could swear Kevin's been peeking over my shoulder, as his brine suggestion is almost EXACTLY what I do (my recipe omits the parsley). I use crushed garlic.
Air dry to form the pellicle (and here's where Kevin and I differ) then smoke plain unrubbed filets over a low heat 190?-200? to an internal temp of 145? to 150? maximum. You'll really be risking too dry if you finish higher than 150? IMO.
I use alder, but anything you like that's mild will work. Be careful, because it's easy to over-smoke striped bass.
I vacuum pack, but IMO striped bass doesn't take freezing very well, so it's best eaten fresh.
Good luck, and let us know how it turned out for you.
