I showed the video so everyone could sort of see the materials in water. I haven't seen many of them in the water since I only use a handful of materials for tails. Probably 90% of my tails are neck hackle. It was good to see the different materials although I admit he used a BUNCH of action and never really held them still except in the current. To me the marabou and rabbit breathe more than other materials when in the water and held still. Like stated above use the material you like and works for you, the fish tell you what they prefer.
