Ahhhh.... now here is a subject I think I may know something about.
Back in the days when I guided here in the Vail Valley, 95% of our clients had never held a fly rod in their life. We did a ton of corporate stuff. You know, 100 folks come into town, do an afternoon seminar, then, "Who wants to go golfing tomorrow? Hot air ballooning? White water rafting? Fly fishing?
My shop got the fly fishers, and they were always never evers.
I learned the hard way that the first thing I needed to do was teach them how to play a fish. I grabbed the leader and became the fish. I got the clients to get the fly line on the reel immediately, and then not to touch the reel until I said "Reel". I made it very clear that the fish might run, but it was never going to leave the river. After just a couple minutes of me running around the field letting them reel me in, then having them let go of the reel when I started to run away and would yell, "Let go!" they would get the idea.
Next, down to the river, and rig up a double nymph and indicator setup. I'd make no more than three or four casts with no more than one rod's length of fly line, and show them how to make a short lob upstream, and a water haul and cast at the end of the drift. It was a one handed deal, the line hand never came into play.
Then I'd get them in the river and let them have at it. I said nothing for at least ten minutes to let them figure out this casting thing. Then I'd start talking about drag free drift and how to get it by raising the rod tip as the indicator came toward the angler, and then slowly drop it as the indicator dropped below and went downstream.
With two or three anglers (never had to do more than three, thank God) on a half day morning trip, my expectation came to be five fish hooked by each person, with three in the net. I really think my teaching them how to play the fish reduced the number of fish broken off to almost zero.
The last twenty minutes of the trip, I would take them back to a field and explain the difference between nymphing and dry fly fishing, then have then cast two rods length of line and getting the line hand into the act.
I got to like those corporate gigs. There was always a tip built into the trip, and when my clients actually landed a few fish I'd almost always get "double grease"
