That is a tough question to answer. Alot will depend of where and when you are fishing. What type of bait is around? Daytime? Nightime? Water clarity? The list goes on and on and you would probably get a different answer from the different people you ask.
Try to carry a variety of differet patterns in different sizes. You don't have to go crazy - your established patters like jiggies, clousers, deceivers, sliders, poppers, siliclones will all have there day depending on what the fish are eating. Big baits - throw big flies, skinny little baits - throw skinny little flies. Try to determine what they are eating and what type of forage in present and match the length and silhouette the best you can. Color can be important, but PRESENTATION will always be your first priority.
Sorry this is not the answer you are probably looking for - but if it was as easy as picking one fly all the time it wouldn't be any fun now would it
Take a look in the Online Store on the front page - Tim has a variety of flies that you could choose from to purchase.
