HP5+ surprised me when I began using it again about 4 or 5 years ago, great tonality and quite fine grain. I used to use it a lot for push processing in the 1970's (pre +) when it was a far better film than Tri-X.

Fast films (non T grain type) are more sensitive to the developer used with them, Rodinal is less than ideal, Xtol would be far better, I get outstanding reuslts with Pyrocat HD
