I worry (a little) that I keep posting flies that seem the same. I don't hear grumblings from the gallery that I should try to be more creative, or "for god's sake another drab #16 herl body?" Not that I worry much about these things, but you brought it up and sometimes I wonder. To answer your question directly, I haven't posted a fly that I would not spend a day fishing and fully expect good results. My flies are often drab, even becoming predictable, which is fine with me. It seems that when I sit down, I nervously ask myself...what can I do to avoid getting skunked? Maybe this, or that. I can answer with a 100%, but I value all the fly that don't fall into that category equally.
The danger and what I think you're referring to is the constant variety of patterns tied seemingly for their own sake. And if we have patterns that work...what's with all the pushing the boundries to the point where it seems the creativity seems more important than the fishing ability of the fly. (I am very likely reading into this based on my own neurosis.

My other concern is with the quality of the tying technique. We often commend one another on beautiful execution of a particular fly. Some of it has to do with what I consider dressing well and combing your hair for picture day. You wouldn't want your kid to have his school pics taken looking his worst, and the same is true for my attempts (I can't speak for anyone else) to show a fly in the best possible light, for conversation...and sometimes a sense of pride. I'm proud of my son and want his pics to be worth sending out to family.

I'm enjoying this thread. And I'm looking forward to seeing where it goes.
