If you want to swing a fly rod around, you can give this build a try: http://www.pishtech.com/pvrs_fly_fishing_beta.zip

I strongly suggest you make a copy of your whole game folder, then unzip this folder into it. Then try fly fishing. Buy a fly rod in the shop, and you'll still have to own at least one lure to start a fishing trip. Maple Valley Creek is there with fly fishing in mind. For now please use only "Paul" as your character when fly fishing.
Note that while walking in this build there's no switching between "walk" and "fish". You can walk while casting, fighting a fish, etc. In time I'll add the ability to "strafe" (step sideways) and support the standard WASD keys used in most first person games. Roll the mouse wheel to let out line (I'll add a non-wheel option in the future), hold down the left button to reel in. You'll notice a lot of things that aren't finished or aren't quite right. Some are little (the fly line is yellow, except on the reel where its blue) and some are bigger (there's no animation for reeling in line), etc. You can at least get a feel for the casting, etc. You can fly fish on foot or from a boat.
In a number of ways the casting is more realistic than in RWFF or with conventional tackle in VRS. The rod flexes with the stroke, loads and unloads, and double-hauling is automatic. The range of motion for the rod forward and backward is automatically limited to an effective range while you're casting so you don't have to worry about bringing the forward stroke too far down. Once the fly settles on the water the rod will lower further and you'll have a fuller range of motion during the drift. I think it feels natural and certainly makes the casting easier.
For new fly anglers, keep in mind that good casting isn't just backward, forward, repeat. It's a forward stroke, a brief pause as the line unrolls, then the backward stroke, another brief pause, then repeat. The ideal length of those pauses depends on the amount of line you have out and the speed of your stroke.
Right now there's no choice of rod weight or tippet strength. Think of the tippet as about 4 pound test. I just landed a five pound brown trout, so it can be done, but even a small fish can break that leader if you aren't careful.
Tight lines (but not too tight),
