Thomas, the base is indeed very different, and appears thinner due to it's inherent desire to curl. I agree that 35mm base should be thicker, but I do not know what MACO uses for their 35mm base, it could be one and the same. If I can get my negs flat within a day of processing, by leaving them pressed in my large book, then I will tolerate this film as the emulsion does appear to behave exactly like APX100 when souped in my favorite dev... Ultrafin. I will check them again tonight. One question I have is that if Agfa did make the actual emulsion for use by 'other' film makers, is there a good supply of this emulsion? I would hazard a guess to say that Rollei is taking a large risk getting into film at this point, and I wonder if the characteristics of this film will change when their supply of Agfa emulsion eventually dries up?
