Some very nice Plus-X samples! Better than I recall, but I haven't used it since 1972. I souped a lot of it in Diafine, and also Edwal FG-7, at higher than box speed, and I didn't like the harshness and grain. I might well have been wiser to run it at a lower EI (my last roll was at 125), and go for tonal qualities over speed... scarcely considered in those days!
