I gave up using HP5 a few years ago (though I still have some left, getting staler by the minute) because I found that when compared to FP4+, it looked "flat" in the higher values: poor separation of details in the near-whites. Its a great film for many applications, but for me it lacked "sparkle" in the high values, where a lot of texture information is conveyed. I believe that it is this characteristic, however, that makes HP5 an excellent portrait film.
