Having shot Type 55 in the past, I grew to dislike their film holders and as such kept to using standard film holders. Now that I am pretty much intrenced in MF, I am again considering type 85/665 for reproductions as well as some of their color film options. My questions concerns your views of the color and b&w print films, as well as any impressions concerning scanning these materials.
I'll second Brad on this - The Fuji FP100C and FP100B pack films are great. I use a lot of both the color and B&W for proofing with my Bronicas and in a 405 holder with my 4X5. Fuji also makes a 4X5 pack film version that I'm told will also work in a Polaroid 550 holder as well as the holder offered by Fuji.
