Very cool tie! I use marabou claws on my crayfish patterns, too but I divide them. When you strip them through the water, the marabou comes together and when you stop them, the marabou flares out and gives a good impression of mass. I usually tie the lead eyes at the eye of the hook. At rest, it gives the appearance of a crayfish in defensive posture and when you strip them, they seem to move like the real ones.
