From personal experience what would y'all say is the highest yielding, short flowering, best tasting sativa out there?? Opinions please..

If you're looking for fast flowering sativa highs, C99 and Green Crack are great, but neither have a strong flavor or smell. They are pretty stealth strains. The flavor they do have is very pleasant, just not overpowering. My personal favorite sativa is Sour D, more of a hybrid really.
I don't grow so I don't know yields, but blue dream (if proper) is one of the best tasting cannabis I have tasted. Plus the high is amazing.
