Yeah, if you feel ashamed to fish with a green weenie, then WHY even fish at all? I mean, the whole goal here is to catch fish, isn't it? so if a green weenie happens to be the logical choice for the given situation then it would be dumb to fish with anything else. Don't make it hard on yourself.
"Oh, green weenies would kill here, but I want to get skunked and fish articulated spent wing sulphur emerger larvae drakes because it makes me look cool."
If the fish want green weenies, give 'em green weenies. If they want brown drake emergers, use that. The better fisherman adapts and uses what he/she thinks would be the most effective pattern. A lot of the time it's a green weenie. For me yesterday it was a parachute cahill. The day before it was a black zonker. Last week it was a green weenie :-D
