You might want to check if it isn't your camera that is doing the scratching. When I first started using Macophot film (Efke) I though that all my rolls were scratched, when in fact it was the camera. It did not stratch Tri-x, which has a tougher emulsion, but it did scratch the Maco/Efke. It turns out there were some imperfections in the rollers. I switched cameras, and the problem disapeared (well, sometimes the new camera will scratch a roll or two if I over tighen it when winding).

Hope this helps,
