Steve,
all modern films are thin emulsion films, but that'a another discussion.
Chris,
PF+ is an excellent film, but if you're used to films with short toes and straight curves, it might take some getting used to. Adequate exposure is essential, and overdevelopment can mean bullet-proof highlights. That being said, I shoot it at box speed, even in direct sunlight, when developed in 510-Pyro or Hypercat. These staining developers do wonders for this film, keeping highlights under control, keeping shadows open, and maintaining that beautiful midtone glow this film is known for.
Grain can be very fine; not like TMX, Acros, or even Delta 100, but finer than 100 speed K-grain films like Plus-X, or FP4+. With a bulk roll to play with, you should have ample opportunity to make it work for you. Enjoy.
