Pastor Ed,
I've been a big fan of quill bodied flies since seeing A.K.'s videos and reading his books because I, too, think they make the most realistic bodies, are very easy to tie with, and float well. A couple of years ago I bought a Whiting Quill Bodied Cape, bred especially for using the quills for bodies, but I don't know if they still sell them or not. I stripped and dyed the feathers using the instructions in A.K.'s book and it was pretty easy, a lot cheaper than buying the quills prepackaged already stripped and dyed. You might check catalogs to see if they are still sold or not.
