the stuff i have at the moment is pretty good, but i'm from sydney, australia, we don't really name our stuff. You buy weed, it's good, really good, or decent. We use sativa and indica to describe the high, and look for the usual signs of good bud - crystals, few leaves, no seeds etc. but basically, you take what you get.
i've never heard a dealer down here refer to a strain by name.
stuff i have at the moment - quite strong sativa, and i haven't had one in a while - makes for a veery nice change from the indicas i've had lately - no more of that, "after 20mins i'm passin out on the couch" - i'm jumping around, far more coordinated, excellent tactile sensations, music wonderful etc. just a really, really pleasant high that tapers off at around 2hrs or so into a very easy, content high until it's all gone. had four cones last night which had me pretty gone
i definitely prefer sativas. but otherwise, i couldn't give a shit about strain, good weed is good weed
