I don't claim to be a great nymph fisherman.
But if you want to try it, don't be intimidated by all the "systems" out there.
You can nymph fish and catch some fish using VERY simple techniques:
Take off the dry fly. Put on some popular pattern, such as a beadhead pheasant tail, or beadhead Walts Worm, or beadhead green caddis larvae. You don't need to change to a special nymphing leader.
Fish where fast, broken water flows into holding water, i.e. pockets and pools.
Cast it up and across, let it drift down though, and watch for strikes. When you get a strike, set the hook.
There are far more complicated techniques, but you can also catch plenty of trout doing it as simply as described above.
I am fairly new to the sport, but I had a couple experienced guys teach me some helpful nymphing techniques. And, while I'm sure I could learn more to catch a lot more fish, I have gotten to the point where I can consistently catch fish on most days. What Troutbert says above is exactly what I do. I will add that at a certain point I got to where I could almost tell when I was going to get a strike based on the drift of my indicator and the seam I was drifting through. I feel that, while fly choice can make a difference, it is more about getting a good, natural drift bouncing off the bottom, thus having the right leader/tippet length from indicator to fly, the right weight, etc...
In summary, I try to break it down to the following:
1 - Reading the water to find the fish (I personally do not need to see them, I just try to envision where they are/should be).
2 - Getting the right approach to the fish so I don't spook them, yet still be able to get a good cast to drift through them (Anytime I can get an across and upstream cast, I do).
3 - Rig my leader, indicator, and fly to get the best drift through the seams (working away from me) while bouncing off the bottom.
The last thing I will add is that I find myself changing the distance of my indicator from my fly a lot to get it right according to the depth and flow of the stream. I keep it between 1.5 and 2x the depth of the water, depending on the flow. I find that longer is better, but too long leads to missed sets.
These are generally the keys to my success, but I too have a lot to learn...
