Thanks for the info on Tmax 100. I did not know that. The shutter speeds of the Speed Graphic, my friend asked me to bring it, and becasue I have a few lenses for it are the driving reasons for me to take it over the Hassy. I have used Ektar 100 and like it, but I think I will still take some 400 with me. We are planning on spending a fair ammount of time away from any citys if we can. With that in mind I think some 400 would be good to take.
