Ray,
You've gotten some good feedback. I've used goose biots for a while and really like them. I ordered a pound about 8 years ago and after sorting through them I have three "grades". The top grade gave me some very long biots which I dye in various colors. The medium grade I could use for flies in the 16-18 range. The low grade I use for tails primarily. Some of the biots are thin and some a lot wider. As a tip, I peel the biot from the stem and either soak them in water or place between a wet wash rag. The idea is to let the biot "soften" by soaking in water and this makes it a lot easier to work with.
