Digital BW, The Print

Hi

Does anyone out there regularly (mainly) use color film to produce gallery quality fine art 
B&W prints?

If so, two questions:

1.  what kind of film and why?

2.  what disadvantages do you find?

as a standard of comparison, I am currently using Plus X.  For samples of my work see 
www.sgraham.com.

I am also familar with many reasons for using color film for B&W (in the digital age), but 
not potential disadvantages.

Thanks
Scott
