FWIW,
I've got a buddy who shoots 35mm + 120 Portra 800, lab processes it, and makes BEAUTIFUL 15"x22.5"(ish) sized optical prints onto Fuji CA and Kodak Endura metallic papers(both cut from 20" rolls). Yes, grain is there, but its beautiful grain, and IMO, doesn't detract ONE TINY BIT from the photographs themselves. Most are 35mm enlargements btw...
He shoots nudes primarily, lucky b*stard
