Comparadun Wing

[Byron haugh]

I agree with Whatfly.
It is not a matter of how you achieve the fanwing.
We often seem to forget that the trout does not see the fly on the water as well as we see it in our vise. When they see a fly on the water, they are impaired by the mirror effect of the water surface, water surface disturbances (waves, micro currents, etc.). They don't see much detail until they are quite close which is often after they have committed.
