I feel stupid asking this but here goes:

I am going to enter the dark and spooky, (for me), world of Classic Wet Flies a la Bergman/Bastian. I bought Don's DVD and some Bourbon so now I have the nerve but I am confused about quills.

Should I be using duck or goose quills for quill wing patterns like a Parmachene Belle when I'm going to tie a size 6 or 8. I looked at some duck quills today in my local fly shop and they looked awful small to me for that size fly.

Thanks in advance for your help!
