Thought for the longest I'mma So/Sx, however, back then I still typed as a Four though. As of late (and with typing as One now) I'm heavily considering Sx/So. Sx-1s, and to some degree all Sx-first, are known to relate to being Fours, even if they ain't, so that would be a sign for being Sx-first. How can you define the best which one's your first and which one's your second instinct? Or what are the clearest differences between SoSx & SxSo?
