@Nesster, I'll chime in my two cents for "Slices"- it says something to me. Nothing wrong with number 9, either.
Coincidentally, I just shot a roll of Portra 400NC out of my fridge on June 16 and used it again for World Pentax Day. I usually shoot Fuji Reala, the occasional roll of Ektar, and most often Kodak Ultramax 400 ('cause it's cheap when it's on sale at CVS and I kinda like it). My lab guy Eddie remarked on it and said "Do you really like the color in this film?" and the short answer is "I don't really know." <g>.

Upshot is, do you notice a real difference between the current version of Portra and its predecessors?
Have to make one more comment on the K1000 - I had never really shot a roll of "good" film through it until this month. Had run a roll of Reala 100 in early June and now this roll of Portra. Still have to say, I'm more partial to the viewfinder and the aperture priority of the ME Super, but I don't think I'll be getting rid of the venerable K1000 just yet...
Best,
Kevin
