Here's one which might get some interesting discussion.
While talking to a friend the other day, he mentioned a person who he said was "one of the top ten" fly fishers in the world.

I had never heard the person's name in connection with any fly fishing "greatness" and it got me to thinking.

Who would you name as the 'top ten' fly fishers? (I certainly wouldn't include either of us, we don't fish enough any more.)

Any names come to mind?
