I totally feel where you're coming from. However, as I've become a connoseuir of sorts as regards landrace, my opinion is that a solid hybrid is generally in order. For example, Oaxacan just feels like you have a blindfold on, so you feel like you need something else to round it out. Thai, which I got in Koh Phagnon, yields like Dr. Grinspoon but is ironically just relaxing. Africans (I'm thinking of my experience with Malawi and Coffee Gold) have a lot of the head trip, but understand you might have to get the plant for 4 months before it's even mature enough to flower.
All that being said, I'd start with Malawi from Ace seeds or a Columbian from Reeferman or Gage Green as they're landraces, but have been pheno selected to be easier. Dig Ace, Snowhigh and some of the others and you should have a lot of genetic building blocks to play with. Best wishes!
