FP4 is all I shoot now. My old fav was APX 100 but since they don't make it in 4x5 anymore I had to find a new film. My favorite soups are either HC110 dil B or PyroCat-HD. I rate it at 64asa for 4x5 and 125asa for minicam (35mm).
I've never been a big fan of the T-grain films. They just don't have the look I like. It's purely personal.
