We keep going back to Calf Body hair. It is very easy to see, does not absorb water easily, and durable. There are a few patterns we use something else, Isonychia (I have a antron that is a great color and is real effective) and Green Drake / Coffin (We use what was called a sail wing. It is 2 mallard dyed yellow-green for the GR Drake or 2 Teal or Gadwall for the coffin that are tied back to back so they stick straight up). In general we use white but for some customers we match the insect wing color or use a color easier to see in the foam yellow, orange, pink, etc.
