Like joesy says, after all the mex brick of the 60's the influx of Columbian in the early 70's was a welcome relief. In the nyc area we would have new choices every other week, golds, reds, khaki greens - all unique flavors and effects.
Usually, the golds were the most "Sativa" like high with an electric energy that kept you moving, smiling, and humming. Flavors did not approach the florals and fruits we get today with modern amenities, but were still definable amongst themselves in an herbal and spicy manner. A bone would keep you engaged for 1-2 hrs with average usage, and even then was preferred for daytime and sexual use because of it's non-dulling and high-ceiling buzz. At the time it was valued at 35-45oz compared to mex at 20oz.
The other predominant Columbian choice were the reddish strains, which were generally darker, denser, sweeter and stronger in a more hard brick. Some used these as an alcohol substitute, best used at night or in groups. Same price scale and a lot of people preferred these on a bang-for-buck basis.
The popularity and profit of the Columbians encouraged other high quality imports like the jamaicans, panamas, premium mexicans and eventually se asians in the early to mid 70's. All unique and engaging, we loved to smoke and review j after j all night long. Generally the debate centered on the more demonstrable "body" high of the heavier strains vs the questing ethereal energy of the "Golds".
All that stuff was ~9/10 compared to brick at 7/10, until the Thai and Buddah sticks showed up at 11/10 and knocked the SA down to 8/10… lol
