I think I was sold on the dual or multiple finish concept by the pipes of the late Bob Hayes. I remember especially a small light stained bent bulldog he did that really appealed to me. I finally bought a rusticated straight Dublin with a bamboo shank, not exactly multiple finish, but multi-material. It has to be done just right or it looks patchy, but you have this one down cold. Keep it in mind in your repertoire. In just the right pipes it has power. I agree, the band gives the pipe dimension that it would lack, and leave it a little too stark. But it's so understated it is really cool, so subtle. Your doing a pipe on commission to specs is like writing formal poetry, it brings up a level of concentration that stimulates rather than quashes originality.
