Again, I don't think of Sour Diesel when I hear NYCD by Soma. Maybe it's the sources of your research that is skewed. From what I remember, Soma did not claim his 'bagseed hybrid' to be Sour Diesel or a cross of Sour Diesel. Maybe I started to hear about NYCD after the dust cleared from some type of dispute but I do remember Sour Diesel becoming popular around the same time.
