A lot of growers don't want to give out their genetics whimsically, AZ or Not, elites are something that some hold close IMO.
Sometimes breeders suggest that a specific strain needs to stay exclusive for certain reasons, i would say gotta respect the originators wishes if hoping to have that connection in the future.
There is early 90's sensi star cut that is probably only held by a handful of Rockey people, the way the masses get that cut is to buy the breeders crosses and pheno hunt, or bring something to the table worthwhile to trade. Hunting definitely takes time and work but that is how the golden tickets are discovered and that is how some cut only strains/ exceptional X's eventually come about. On top of that, if one takes the time to research breeders intently, stalk the drops, undoubtedly they will find the individuals that will have fire in every pack.
If I have learned anything in this industry It's all about establishing relationships and proving worth before asking for favors. Good things come to those who work hard and wait patiently.
