My roomate has been talking up the new 400 TMax like you wouldn't believe, and I've seen some wonderful things out of it, so I'm not too inclined to argue. However, he seems to keep around 400 for it, though he says it pushes well. My main thing has been TriX in Diafine at about 1250. Does anyone have any experience with how well diafine takes to the new TMY? Or just how well it'd push up to that range, grain/shadow detail all that mess?
