Can any one tell me how the Duke 1 or 2 compares to the Rooney 1/1 in Silvertip or Super Silvertip? (I assume these two differ only in color.) It's for face lathering soaps. Is one firmer, scratchier, a better lather maker, etc? Is the Duke really better, as it is always mentioned as "the " brush for soaps? Assume they are equal in price for this argument. Thanks, Dave P.S. Does the Simpson Commodore belong in this comparison, or are we talking minor vs. major leagues?
