120 film and all that jazz

So, on a photography-related slant, I’ve just bought five rolls of 120 film for my new Holga. Here they are, in all their glory:
- Ilford XP2S ISO400 B+W
- Fujifilm Neopan ISO400 B+W
- Fujifilm Superia ISO400 CN
- Fujifilm Reala ISO100 CN
- Kodak TRI-X PRO ISO400 (B+W)
Expect notes (and hopefully photos) on how they compare. This is my first adventure into non-DSLR territory, so I don’t really know what I’m talking about yet, but hopefully I will soon…
