Looking for some suggestions for flies to tie up for my trip to the Keys. I leave Sunday so I won't have time for too much, school and finals week has really cut into my prep time more than I expected. I'm not sure what kind of fishing my dad has planned, and I'm sure the guides can provide flies, just wanted to have some for the times we aren't out with a guide. Any must have flies that I can tie that don't require any specialty materials?

I'm sure I'll be buying some flies there, just figured I'd get some together here first. Species wise, I'm open to flies for anything that can be caught down there, I'm not picky when it comes to what I catch. I'm guessing a good shrimp pattern and a good crab pattern would be good, I've got clousers and deceivers already for baitfish, but I'm still searching for an easy crab and an easy shrimp. I plan on tying up some Electric Dreds when I can get the materials for them, but I'm not sure I'll be able to find them between now and Sunday so not for this trip most likely.
