As usual I'll have to be the odd man out on this one. I lived in Colorado a few years and got so tired of catching nothing but trout that if I don't ever catch another one it will be fine by me. What I do enjoy doing with a fly rig is casting the bank edge of a pond or lake. Most of what I catch are Bream or a variant thereof or sometimes Bass. I have even caught Crappie and White Bass casting to the bank in the spring.
There are advantages, there's nothing behind me to take my bug!!! My rigs are simple, I have 4, 5, 6, 7, and 8 weight rigs and they all have their place and time. 99% of the time I use my 6 weight with a level, floating line and only use a sponge spider that I tie myself, primarily because you can't find a decent one that lasts more than 2 or 3 fish.
Jan's Netcraft is an excellent place to find a bunch of things fly related and all of my supplies for the famous Sponge Spider come from there. Fly fishing is fun and frustrating, all wrapped up into one.
@spittinfire if you want to try my methods on Lake Norman holler and we'll go one day....
