I've read reviews on the Supersite- it's Lith film with a slow developer, as I remember. Just like the Kodak product. It's great if you use self blocking processes like POP but it's LONG tonal scale means that it's hard to print it well, from what I remember. I've used Tech Pan this way, and have either had to print it on HARD paper compressing everything, or had decent results on POP, after toning the negative.
