Anthony,

Just another perspective. I've experimented with shooting B&W 
traditional film, B&W c-41 film, and Color negative film for B&W output 
on my epson.

The clear winner for me has emerged as color negative film. I like that 
I can choose which colors to "throw away" when converting to grayscale 
using the channel mixer.

And, making selections while the image is still in color--often much 
easier. Not to mention using the saturation adjustment on selective 
colors to to change the tonal response of just those colors.
