Andre,
I have 3 Hoffman #1 saddles, grizzly, Dun, and brown. They are great for tying size 14s to size 18s, as Larry said (very stiff with lots of barbules). I think Whiting bought out Hoffman a couple years ago, but not 100% sure. To give you an idea of how long the hackles are, I tied 7 or 8 Griffith's gnats from one grizzly hackle.
