Depending on the size of the flies you will be using, I would recommend a 4 or 5 weight fly rod. If you will be throwing big streamers and dries, you could go to a 6 weight, but it makes the small ones a whole lot less fun. If there is a lot of brush around your creek, and it is difficult to make a long backcast, i would use an 8' rod, if it is more open, a 9' would be perfect. unless you are targeting huge browns or rainbows, or plan on doing some fishing for species that tend to run a lot, a click pawl type fly reel (no drag, only a clicking brake system) would be perfect. If you plan on fishing for bigger trout or harder running fish, a disc drag reel (similar drag system to a spinning reel) would be better suited for that. A weight forward or double taper floating fly line will be perfect for most fly fishing, unless you want to get a big streamer down deep on big rivers or lakes. The line is the most important part of the setup, so buy the best you can afford. The rod is the second most important, and the reel is mainly just for storing line unless of course you get into a big strong fish. Everyone has thier own preferences on rods, so go to your local fly shop and hold a bunch of different rods until you find one that feels 'right'. As far as brands go, St Croix has some good fly rods, and an awesome beginner fly rod is an Orvis Clearwater. Orvis reels are also great, as are Hardys and Sages. In my opinion, RIO makes the best fly line, but as I said before, everyone has their own preferences. Buy a few tapered knotless leaders, some tippets from 3X to 6X, and a good assortment of wet and dry flies, and go hammer some trout. Hope this helps!
