Just ask around for a good sativa or sativa dominant strain. That stuff from the old days you like was 100% sativa. The seed breeders bred in indica to shorten the flowering cycle so growers could have more crops in a given time frame.
Look for a popular strain called "Girl Scout Cookies" - Supposedly has roots (pardon the pun) in the old Mexican lines.
Or just ask Jeff_O. He grows legally. He said he'd hook anyone on the 'fire up.
