Here's one that works good for me.
Hook: Sz 10
Tail: Brown Marabou
Rib: Small copper wire
Thread: Orange 140 denier
Eyes: Bead chain
Legs: Hot tipped silli legs - Black/Red
Tie on the bead chain eyes on top of the hook, useing figure 8 thread wraps about 1/8 inch back from the hook eye. Then wrap the thread back to just above the barb of the hook.
Tie on the tail, then the copper wire and the hackle.
Twist the brown marabou and wrap it to right behind the eyes.
Tie it off and clip the excess.
Wrap the hackle to behind the eyes. make 2 or 3 wraps of hackle just behind the eyes and tie it off. Clip the excess.
Counter wrap the copper wire rib to behind the eyes and tie off. Clip or break off excess.
Make a couple extra thread wraps behind the eyes and put in a half hitch or two. Move the tread in front of the eyes.
Tie in 6 peices of the silli legs on the under side so the black part extends over the point of the hook. Clip the legs so they are as long as the hook shank. I like to have about half black and half red after they are cut to length.
Make a head and whip finish.
I've caught carp, cats, bass, bluegill, drum (sheephead) on this fly. I think they take it for a crawdad.
