Bought this hook in a size 2 for a clouser type fly and immediately I liked it. The shape is similar to the B10s, but the wire is a tad bit thicker in my opinion, which I really like. I also like the way Ahrex sizes these compared to the B10s. Just enough difference between a size 4 and a size 6. I've used these now for clousers, baitfish patterns, and small craws and it really gets the job done.
