For those who are new to the sport, a good way to begin is by wet fly fishing as opposed to dry. Wet fly fishing simply means that you use a wet fly instead of a dry one. This takes a lot of the pressure off casting perfectly. The fly in this case doesn’t have to land just right on the water because it’s not imitating a live fly. It is more or less either an imitation of a stage of life of aquatic insect, or a representation of a drowning fly. This kind of fly fishing gives you the opportunity to still have the chance of catching fish while simultaneously practicing your casting accuracy and technique........
Fast Action Fly Rod: This fly rod is stiff throughout it's length producing a limited amount of flexability. It is designed to cast further and catching bigger, heavier fish. It's not good for fishing in a small stream, or for catching weary trout. This is because the rod does not handle light tippets very well, which are generally used for catching trout.........
Medium Action Fly Rod: Just like its name suggests, it has a medium stiffness to it. It is more flexible than the fast action fly rod, but not as much as the slow action fly rod. These are the most popular among fly fishers because they are very versatile. They are also good for people who only want to invest in one rod. This rod works well for both advanced fly fishermen and beginners.........
Slow Action Fly Rod: This rod makes short, soft casts. It is made for tighter spaces and will provide a lot of accuracy on a short cast. They work extremely well with light tippets, which are what you use to fake out the weary trout. It makes the fly appear more natural and will provoke the trout to think so too. This rod is good for beginners because of its accuracy and is used to reel in the smaller fish.........
I hope this help you a little!!!!!!!

Once you get the hang of your cast I strongly suggest using a droper rig, which consist of a high floating dry fly and a nymph pattern tied off the eye of the dry long enough to drift a coupl feet off the bottom. I like using an adams dry fly with a copper john dropper. You could also do a hopper patern and a wooly bugger. If you use trial and error to find the right combination you will double the amount of fish you catch because you can fish different levels in the water column.

The best thing to do at first is learn from somebody experience. The most cost effective way to do that is have a friend take you. But, if none of your friends are avid fly-fisherman, the money invested in a good guide is money well spent. In an afternoon- a guide or experienced friend can teach you enough of the basics so that you can go out on your own next time and play around. I honestly believe that the best teacher is no teacher- playing around, seeing what works for you, improvising, figuring out casts you are comfortable making. But, in order to do that, it is best to have somebody experienced help you get your bearings at first, especially when it comes to presentation and etymology.

Toutrageous,
First, just be ready to learn. Don't be afraid to go to a fly shop and ask some questions, they'll usually give good advice. Do whatever you can to learn as much as you can....read books, ask more questions, and you can even watch other people fish. But most importantly, just get out there on the water and mess around, you'll learn a ton and before you know it you'll be snagging a few trout. Also, some advice...learning how to fly fish is frustrating at times, but stick with it.
