I usually like to ask the strain name just so i know. most of the time my guy knows, sometimes he doesnt.
i try to keep track of strains and what they were like. next time my guy has it and i have a choice between a couple different strains i know what to choose.
as for the indica/sativa ratio i dont care to much, but one thing i always keep in mind, if its kush or heavy indica, those always seem to kinda kill me.

most important though is price. the one thing that REALLY matters, the rest is really mostly fun, cause in the end it all gets you high
20 a G - bomb nuggets
15 a G - some decent stuff
dollar points - it gets you high and aint total shit
