1 yes they are all still around..in there place of origin. And anumber of vendors as well.
2 I think you could recreate most of the flavors and highs from long worked varieties. Time, luck and numbers is what it would take.
I have a few, not enough, the effects in some, are mellow. While others are devestating and could hold their own in todays heavily worked varieties. I will in the near future obtain most of the available sat. From as many different vendors as possible. Then the work begins in making f generations while selecting for superior individuals. That will not be in the near future
Great luck to you bud.

I have great confidence that you would create some really impressive standouts from the crowd. If you then ripped a page from the story of livestock domestication and inbred repeatedly for desired traits, you'd be knocking on the door of a whole new subcategory, with as much uniqueness to its makeup and profiles as 'sativa', 'indica' or 'kush'.
The only limits would be the traits you're breeding back for and how many generations to do it.
I had that Colorado cut of Maui Wowie too, homebrew's assessment was on the money. I was going to add that it got extremely bushy on me, needs a lot of thinning and shaping, and it took for-ev-er to finish. I gave up on it after 12 weeks, I just don't want to wait that long on a crop. That's why I let it go. There was another sativa dominant cut running around Colorado at the same time, though- it was mislabeled as Master Kush when it was sold to me. Anyway, this one finishes in 9 weeks and is better than my old Maui Wowie in every way. I'd love to ID my cut, just to satisfy my curiosity!
