Thanks!
Now I understand how to tie Francis and Frances too

Standart fly has very stiff and long antenna. I think it is Island style for double hand heavy fishing. Sometime we need more delicate flies for 1,2 - 1,5 meters deep water. And effective fly I was talking in 2010 has accent on cock feather palmering body, not stiff antenna. It allows fly to start to provoke fish in a not very strong river current. Less weight -alu and plastic tubes and small size double hook. Treble hook is prohibited on Chavanga river C&R fishing.
I try to change body color from fl.red to claret to get info about resident and silver fish reaction. And what about tail? It may be very important too. Red (body)- black (tail) combination is very effective.
