Excelent fly, very nice photo!
I tested some pool chemicals with chlorium to de-flue peacock quills. It makes them more fragile, but can be tied with care... You can make hundreds of stripped quils in 10 minutes. It maybe will help
Thanks very much guys!!! These flies can be tied until 10 minutes each, nothing difficult.
