i tend to agree with tip top toker on this one... first of all, about 90% of todays' genetics all come from these so called shit strains, so what does that tell you?? i don't buy into that monkey argument either, but that's just me..
i'm not saying the weed back then was better, but you have to remember none of it was grown indoors under proper conditions like what we have today.. now a days, people have complete sealed rooms, co2 enrichment, super hps blue enhanced bulbs, advanced nutes latest and greatest supplements to bring out the very best in the buds, grow tents, etc, etc, etc..
back in the 70's, that bud was grown out in mountains and fields with lil care.. seeds were planted in spring, and people would come back at harvest season and chop what had managed to make it that far.. males were common, seeded bud as well, not to mention things like drying and curing.. a gold is said to have gotten it's golden color from being cured out in the mexico sun.. today, we realize that exposure to light degrades thc.. imagine the post on riu where someone said that they're drying they're bud in the cali sun to give it that golden color?? they'd get laughed off of the boards..
then it comes down to packaging and transportation.. lil care was taken as they put keys of bud into anything that would hold it to get it to where ever it would eventually be sold.. today, i doubt most of us are 3 or 4 people away from the person who grew it, if that far, and those people take extreme care in the way that they package their buds as well..
i'd love to have some old skool gear and grow it under the premium conditions and compare it apples to apples to todays weed and see what's the dillio.. really the only way to do it..
