Kind of agree, at least with reference to the body. I also agree that the hackle can be overdone, but I don't like what I would call sparse.
Colors WW? Black on black, brown on brown, ginger on ginger, yellow grizzly on yellow, olive grizz on olive, and grizz on black.
Ginger is by far my favorite.
Colors for WB's, black, olive, Sculpin, and brown. I tend to like solid color buggers with bead or cone heads.
