Here's the original concept from Bill Woods. Mine are solid cherry comprised of 12 "petals" per horn. I've not heard anything better but that rather brash sounding statement should be qualified by the fact that I'm not much in the game anymore nor do I get out much to hear alternatives. I take some encouragement, however, from the Cogent guys and OMA, both of whom have turned a lot of heads with Bill's horns.
Mine could be for sale if someone is interested and the price is right.
