I played with it for a few minutes and it was golden. I have had problems with black half-moons on my Rangers and it just drives me completely nuts - I have not had any issues with the Promasters at all, thank goodness.Frank, thanks so much!! Maybe Zen ED's need to visit Arlington for a little while! If I am reading your comments right, the Zen's have an edge over both the Hawkes and the Promasters in a couple of areas. Hmmmm......I feel a visit to the Zen site coming on!! Do they really wait til February to ship?</blockquote>
