Strung hackle comes from saddles - it's usually the inferior webby grade that is not usable for dry fly techniques. However, saddle hackle has created a niche for itself for salt water flies, some freshwater patterns, and – a lot of jig patterns.

The duck and Guinea feathers are better suited for collaring as opposed to palmmering.

FM - Like the Whiting and Keough also - lot cheaper buying the patches...
