Hi

I've used both Ilford HP5+ and kodak Tri-X 400.
I've got better results with the Kodak but I think only because of the process. I went to Atkins Technicolor (in Adelaide), and they did a really nice job, even if it cost me 43$ (process & print 13x18cm).
I got my HP5+ processed in a cheap shop back in France, and wasn't really happy with the results. I guess I should have another try with this film & a good process.

So as said GlennSan, take care of the process & show us results
