An experienced fly tier once told me that he ties all the same flies in any given session and throws away the first six.

I don't quite do that. But it takes a few flies to get the proportions down for me. Offhand, I think that clouser isn't that bad. But it will look more like the traditional clouser if you use bucktail, and (of course) flash.

The clouser is such a great creation. Very unlike anything that went before (as far as I know), simple to tie and effective. Hard to cast, though.
