Just shot and processed my third roll of CATlabs 80 120 film. I like the look, the base is very clear--not sure what the material is (mylar?), it is certainly not the same as Kodak or Ilford. There is hardly any curl from being rolled up, and it makes it a bit difficult to load on the developing reel--other films stay rolled up when removed from the spool, the CATlabs sort of relaxes and can't be easily gathered in your hand. Which for me means the film can possibly touch the table or floor and pick up some dust while loading. Also, this last roll was on the short side. The last frame ended up right at the end of the film. I have never experienced that with other brands.
