Have a look at the 'spanish olive' image in my gallery. Acros @64 in Dixactol. I would imagine that Pyrocat HD would be the same, namely incredible acutance for such a smoothie film, with invisible grain (contradiction in terms I know). Undoubtedly a modern tabular film, but IMHO much more attractive then TMAX100. It is in a completely different league to Tmax of delta in terms of grain, there aint none (which causes problems in regular devs if printed to small size as image lack edge.)
Oops, spanish derelict and llyn cwmorthin are also Acros in same dev
