I know everyone works hard on the flyswaps, and I appreciate all of the
work. Tyers, Swapmeisters, Photographers and Webpage managers all have
done some incredible jobs. One thing I would like to ask, what are your
three most productive flies that you've copied from the swaps? ...

Willi's emerger is by far and away the most productive.
I also copied Tom Littleton's version of the Usual and
it's been productive too.
