I think Delta 400 would be a good choice, but I certainly wouldn't rule out HP5+, Neopan 400 or even Tri-X. All of those developed in FG-7 /w SS will deliver excellent speed (400+), high sharpness and pretty fine grain. I find TMY the worst match for your needs. It's slower than the other 400 films by at least 1/3 stop and it has such a short toe, I can just imagine the trouble you might have trying to print sooty, (flat!) black trains from TMY negatives.(posted 8223 days ago)Also, if you feel like experimenting, I've done a few tests with FG-7 with sodium ascorbate added that look very promising--very sharp, fine grain and smooth tonality. As a starting point use 1/2 oz. FG-7 to 15 oz H20 and add 1/4 tsp sodium ascorbate. Develop FP4+ for 7 minutes @ 70 using continuous agitation. I'd try adding 25% to the time for intermittent agitation, add another minute or two for HP5+ and Tri-x, one extra minute for Neopan 400 and minute less for Delta 400. This should put you in the ballpark with all of them.
