Nice colours on those! I got some of the new "impossible" packfilm but from what I saw in the shop the colours are not going to be as good - very desaturated.
It is nice they are still making it. I wish they still made the 4x5 size (FP100C45). The rear springs are what cause trouble with the FP100c packs. the polaroid packs were metal so could tolerate the spring tension better. The fuji, being plastic, deforms under that spring pressure and jams, resulting in binding internally in the pack.
