I've found the Kodak paper is very tolerant and easy to fine tune as +/- 10 or 5 units makes subtle differences. I'd read before that Fuji paper was narrower in tolerance, needing just 1 or 2 units for Kodak's 5 or 10. At the moment I'm very happy with Endura and Edge is also nice (but thinner). Toward the end of last year there were rumours of Endura's demise and talk of Fuji coming back in sheet form (via a 3rd party). I hope the Kodak papers continue as switching to Fuji will inevitably mean changing my habits and having a steady hand on the colour dials.
