I think somewhere in SamS's pics there is a scan of an article from a '60s/'70s Southern Californian newspaper in which there is an interview with the Haze Brothers on the evolution of Hazes. The impression I was left with (I read it while baked a few nights ago) was that Hazes have genes that reflect whatever the good sativa grass coming into Californai over all those years was - and on that basis I am not persuaded it is possible to establish the range of different sativas that went in the mix... ont least given the diversity of cultivars in the various countries of origin, but especially not retrospectively
