Digital BW, The Print

I see the term "bronzing" used a lot here, but not sure that's what I'm 
seeing, since it's usually used for slick papers, and seen from a 
certain angle etc.  I use the technique of printing from a grayscale 
image and adjusting the sliders to Paul's recommendations.  Still, on 
many prints, I get a distinct bronze tone in some areas (it's really 
there, not just in some light or at some angles).  Should I go the 
other route and do the grayscale to RGB then use curves, and if so any 
recommendations on settings?  I'm using Epson Enhanced Matte now, if 
that matters.

Thanks

Michael
