Oh I totally agree with you, bro --- but I'd say gg4 and Gsc have been a big part of most breeders projects in the last few years, not just Myko. If you are looking for uniform results with no surprises, you shouldn't be shopping for polyhybrid breedings in the first place, no matter where you buy them. That doesn't mean they don't have value to the community. Most people in the world will not ever even see a true GG#4 cutting, or any other "real" cutting, and giving them access through a poly cross is as close as they can get. Yes, you might never find anything exactly like the parents but there's also a chance you could find something you like even better. To me, the dankness is all that matters, not the name.
Also totally agree with the all the "cookie" cuts out there. I got the forum cut, prolly the most common of them but at least I know its real. No telling how many s1 strains of gg#4 and gsc are floating around under the guise of the real deal. At least DNA mapping seems to be on the way.
