I agree with the speed crowd. I like TRI-X - although I still keep and use FP4 for situations where I can use it. I agree that TRI X is good for 16x20 but for larger, I would prefer the FP4. My experience was at the beach - trying to capture the waves and being forced down to F22 and I lost DOF and was not happy with any of the negs. If I had film that was a few stops faster, it would have been ok. - Oh yeh - did I mention wind? So I use Tri x outside and inside (or when it is really still), I use FP4. Don't have too many - get really good with a (very few) couple of emulsions and spend your time in image conception and creation.
