Durbin - I'd suggest Ektar for resolving critical shades of brown like occur with mahogany, provided you carefully balance it per color temp meter readings. I can be
printed on Fuji Supergloss for the same kind of look as Cibachrome. But ideally, you need to know some masking tricks just like Cibachrome, only different tricks. But
the end result can skunk an inkjet to pieces.
