This is your best bet for palmered bodies and for hackle on larger bombers. Althought it is not as long as the hackle found on most saddle patches, it is a little wider, making it better for larger flies. A typical package of saddle hackle will contain a number of feathers as shown above, as well as several "spade" hackles which are webbier and not as useful. Some folks simply disgard them but others find them useful for streamers, beards and tails.
As the name suggests, this is taken from the large rounded feathers found at the back of a rooster's neck and is useful for wings on large streamer patterns and some salt water flies. They are not suitable for use on Bombers or other dry flies.
This is a very webby rooster feather which is not suitable for conventional hackle applications. Some tyers prefer to use a few fibres to form a "beard" in place of a throat or collar hackle on salmon wet flies. Others find it useful for tails.
