that's not easy to recommend the colour negative film to switch to, but may I point to Fuji NPH400? It's a wonderful film, extremely consistent in colour balance/saturation. Personally I switched long long ago from AGFA directly to Fuji line, and I'm VERY happy - the whole range is outstanding, NPS/NPC 160, NPH400, NPZ800 and my favourite NPL160, tungsten-balanced. I print all my color negs too, and it's always the same basic filtration. Give it a try, I hope you wouldn't be disappointed. The skin tones of Fuji NP line are especially good, on my opinion.
