My cousin, age 19, with his first LMB on a fly rod.
I tied on a leader of eight pound Berkeley Vanish fluoro, of which I have a lot. And I made the leader a lot longer than I usually would -- nine feet, same length as the Echo nine-foot six weight I bought him last year. The fly was a size 10 Bass Vampire, a heavy purple thing that sinks like a stone.
The idea was this: The bass are sulking on the bottom because it's been so hot. The lake isn't that deep to begin with. He's in a float tube and moving most of the time. So let's get the streamer down to where it is close to the bottom (20 feet give or take where we were) and the worst that can happen is it gets caught in a clump of vegetation.
Caleb has gotten to the point where he can adjust his cast for a heavier fly/longer leader. I accomplished this feat of instruction by presenting him with a heavy fly and a longer leader and telling him to get on with it.
Next lesson: How to handle fish.
