I am an intermediate tyer and do not worry so much about what kind of feathers I use (yet) as long as they are the right size/color. As you develop your technique and get a good grasp of the basics you can build on it and start to gather more "proper" materials. For now, I often still use lower grade feathers for nymphs, streamers and dries (especially parachutes) and I still catch fish. For buggers I use cheap strung saddle and the fish haven't complained yet! This guy was caught on a Para Adams that was tied with cheap hackle. After the first couple fish the fly did not want to stay on top but they still hammered it anyways.
