I don't know why, but I've always hated HP5. The way I hate the Mets, ya know? It's got too much contrast for my development style - edges look like have USM built in! While I find Ilford's t-grain films to be superb, none of their traditional grain films please my aesthetic. With Kodak, it's just the opposite.
yeah... the short experience I've had with HP5 was a very positive one. Once I end my experimenting with APX100, I'll probably move on to HP5.
And on a similar note, I once pushed FP4 to 400 (that was before I learnt you are not supposed to do that...) and I got some VERY nice results almos absurdly high contrast!! (which btw I usually love).
Shot my first roll of Delta 100 today, gonna process it tomorrow morning. I printed a really cool shot from my HP5 roll today, gonna try and bring it home(not really supposed to) tomorrow o scan and then bring it back.
