Re: Saltwater question
Never been to that area, but have fished tidal water my whole life. You'll likely be fine with what you have, and sounds like you've covered it well.
You might want to add some darker colors for your Clousers, Deceivers & Seaducers, as you never know how conditions might change during your time there.
Don't know if this relates or not, but I used to tie a lot of Tarpon flies for guides down there in FL, and was told that what was regularly used in the Gulf, was not the same as was used in places like the Keys, as there was a difference in water clarity.
I've experienced enough days that dark patterns out fished bright. Even if you only add a few all black or black with some other color, or some with brown, olive or purple grizzly in them. Perhaps some Cockroach patterns. Then you'll have something else to try if the bright colors don't seem to interest them.
Remember, no one likes to be behind the big truck, but that's better than being under it!
