I don't use TMax films any longer, but I've found that the highlights withDelat 100 & 400, and also HP5, in Pyrocat HD in cases of extreme highlight contrast have been easier to print with better detail and less prone to what I guess you calling blooming - light scatter/halation.
So Ian, is this because of the curve shouldering, allowing the image to fit the paper curve better?
