Hi Alex,
I think you can squeeze ei of 200 out of JCC 200 in PMK. I shot some like that and it looked ok but I liked the shadow detail better at 100. I get full box speed out of Hp5+ with PMK. The only reason I have tried JCC is the glowing reports here on APUG.ORG. It is a nice film. I was in a lot of wind last weekend in very north eastern NM. I asked someone if the wind always blew like this and he said, "No, sometimes it blows from the other direction". I have been in wind in southern AZ that actually blew my camera over. Nothing would have been useable that day. If you need any help with PMK let me know and we can talk about the problems. Don can read the densitys for you if need be.
