I like marabou patterns like this! I'll share a few since I'm at it.
One pattern I like a lot of gartside's soft hackle streamer...somewhat like the yellow, pink, orange above. Only I used pheasant soft hackle feathers. I love soft hackles quite a lot -- it seems to displace the water just enough to seem "alive" or something. I figure any way to mix it into a streamer pattern must be good ;)....though mine are hacked-up versions of what they probably should be.
You've convinced me to add rubber legs to my palmered marabou patterns like that pheasant leech. I think it works like a charm on woolly buggers, like the fairly ugly one tied above on the right.
Catfish seem to like it anyway!
