Hi Eduardo,
Can you elaborate on what you mean by "the super neutral response of the diffuser fabric"?
Many lighting modifiers have a big problem, they add some sort of cast to your lighting and that pretty much mess up with your white balance, as an example the interfit 24x24" softbox gives a really nasty magenta cast to your photos it could be either the silver interior or it could be that the diffusion fabrics do fluorescence, I have the photek softlighter II and the cast it gives is minimum -and it is towards warmer colors- but elinchrom modifiers are raved because they wont have shifts or casts your white balance will be impercetably affected when you use one of their modifiers.

that I am now saving up for 2 600RX & 1 1200RX (to beat back the sun when needed), the Elinchrom wireless system and of course modifiers 
) for making this place jump with a wealth of info that a class or book just doesnt cover.
