Davy, you might need to explain the term "coarse fish/fishing" for us yanks.
I agree with Davy's position on the harvest/wound ratio of non-lead shot. I had a fly-shop customer in San Antonio who owned a very large ranch south of Victoria, TX. He switched back to using only lead shot while duck hunting because he had to watch multiple ducks limp around his ranch after being wounded by steel shot. They couldn't fly at all. I can imagine he felt bad being directly responsible for that, and didn't want to have to watch it again.
For any doubting his conservationist credentials, you might want to take a look at this article: http://www.tpwmagazine.com/archive/2002/sep/ed_2/
Same guy, quite a character!
