Digital BW, The Print

Steve,
Channel Mixer really can make a difference. What convinced me was recording
a Photoshop Action to automatically create a grayscale snapshot  that's 100%
red channel, then 100% green, then 100% blue. You can then easily flip
between the 3 snapshots and clearly see how the results differ by channel
(and therefore which channels to emphasize or de-emphasize in the final
conversion). Obviously the results will be different in digital, but in 35mm
it can make a dramatic difference in grain structure, skin tones, etc.
