yeah who knows what you are even geting these days with all the different white widow strains out there. it's supposed to be sativa dominant.
good choices imo are:
silver haze (or super silver haze (super silver has more indica in it than the original i believe), or anything with "haze" in the name, neville's haze is supposed to be the shit)
nyc sour diesel
strawberry cough
jack herer (1/4 seeds will be indica)
most "connoisseur grade" cannabis will be sativa dominant, remember sativas are always more work, less product, less overall potency... but give that intense cerebral high that true tokers love, that trippy energetic euphoric high... also usually high paranoia factor unfortunately
look around for the original haze, it's PURE sativa and will easily get to 7 or 8 feet, it has a VERY long flowering period though, like 14 weeks but if you're willing to wait i'm wiling to bet it's worth it
