Core wise, I've gotten all the heads. A head type isn't impossible, but I think a shame or gut type would fit me better. I've never typed as a core 6, but have typed as a 6 fix for awhile. If I was a core 6, I'd say 6w7. Attachment core and the apprehensiveness of the 6 and the curiosity and indulgence of the 7 wing. But yeah, the motivations and fears and core wounds just don't hit as home as my other numbers so I don't think it's my core. A few people have seen me as a 5, I do have a lot of intellectual pursuits and I'm pretty introverted but beyond surface level traits I don't think I'm a 5. I've typed as 7w6, which I think people got cause of my tastefulness and me being scared of pain and silliness. But yeah, there are things I fear more on a spiritual level that fit other enneagrams better. I don't think an introverted 7 is impossible, but it's still a little oddball.
Tritype wise, I tend to get any of the 96 types. I think I vibe good samaritan sometimes cause I have that soft vibe, but eh, I don't have a huge desire help others. And if I do, it's not to get love, it's cause I think it's a nice thing to do. I've also gotten and tried on triple attachment-I am pretty high in attachment triad and I do care about being successful but in the end I think my 3ness compliments my 4 so it's better as a wing. Like I believe to be the most successful in life I have to be unique and get in touch with my inner self. Triad wise, I lack competency, I'm far too introverted to only be single withdrawn and I'm definitely not frustration blind. It's interesting I type as seeker now and head last since my heart was all over the place but it the end it was the triads I was worried about and not the motivations. I also vibe gentle spirit to a lot of people, and that's the first tritype I've ever typed as. I do worry about being deprived like materially so I've reconsidered it as a fix. Triad wise though I'm not very expansive and double positive is too much. I think my 6ness tempers my 7ness in a way that is too strong for a wing.
