Oh I don't doubt that they catch fish. I just don't have the patience to tie them. Classic patterns are akin to what a painter puts on a canvas. The things I put on hooks are similar to 3 year olds drawing on walls.
P.S. - I personally don't like dumbbell eyes on my streamers. I find you get much better action without them.
P.S.S. - If I didn't spend my days casting a 10wt with 12+" meaty streamers, how else would I get a workout? It's much more fun than the gym!
