I've just shot my first roll of this. In general colour balance good, white snow is a pretty good test and did not experience overall yellow cast although in a few frames there are odd yellow bands, see the second attached photo. The lab offered to re-fix but it was just a test film so I didn't bother. So maybe the film is sensitive to the fixing stage, (they showed me another film from the same processing batch and it was fine) or there is some sort of manufacturing fault. I'm not up on E6 processing so can't judge.
