Your tritype is tough, Lady X.
First off, tritype is not all that technical. People try to get all technical with it, like lay out "how it works", depending on what order the fixes are in, and what your instinctual variants are, etc, and, well, frankly, it rings of bullshit to me. Not saying an individual couldn't figure out how their own fixes work within themselves, but I don't know if that will be by any means universalizable to all other people of that same tritype, etc.
So, with that caveat, I'll say this: 729, 749, 728, 748.
That's probably the order of likelihood I would put these things.
I think you're more of a 9w8 fixer than actually having a full-blown 8-fix.
And, after your core 7w6, I would say the thing I'm most certain of is just that: your 9-fix.
It's really the 2-fix or 4-fix that is most difficult for me to figure out.
You're so upbeat and positive and other-oriented (not entirely, by any means, you definitely have a sense of self as well [which is what makes distinguishing the 4-fix from the 2-fix difficult, really, cuz 2s are often associated with kinda not really knowing themselves, I feel, and you don't really have that {lol... except you did just ask others to type you, didn't you?

}]), and I think that speaks a lot to 2.
But the possibility of a 4-fix is there too.
Part of the problem is that it's not your core fix, and it very well may be your weakest fix, so you'd expect it to probably be a bit more difficult to get a handle on (the "volume" on that channel is just not turned up as loud); another problem is that 2 and 4 share a line of connection, with 4 disintegrating into 2, and 2 integrating into 4, so that could further muddy the waters.
I'm certain you've already read these over a bunch of times, but these posts really are essentially the holy book of tritype (which goes to show how little has really been published on it), and the best way to figure out which you are (if such a thing is really even that important or necessary), is really to just read these profiles, and figure out which one fits you the best.

Silly was a 478 ("The Messenger"), and just think how much more of both a depressive as well as combative element she had to her (albeit while still having lots of positivity and friendliness most of the time): that's the 4 and 8 fixes. And it's why I just feel more-or-less certain that that one is, without a doubt, the least likely of the three. 278, ("The Free Spirit"), is perhaps a possiblity, because the 2-fix kinda might take the edge off the 8's tendency towards combativeness and attempted domination, but, I dunno... I dated an ENFP who identified as 872 (8 was the core-fix, tho), and I just don't think you have the sadistic murderer's streak kind of 8 quality that she could have.
So, yeah, I really see it as being between a 279 ("The Peacemaker") and a 479 ("The Gentle Spirit"). Both of them make sense, strictly from a name-of-the-archetype point of view. But look at the descriptions a little:
479 Description said:
(4)-7-9 - The Positive 4
4-(7)-9 - The Withdrawn 7
4-7-(9) - The idealistic 9
"The Withdrawn 7"? Is that really you? I dunno. I only see you on here. Maybe in real life it is.
No such little naming thing like that exists, apparently, for the 279, unfortunately...
Here's one for the 278, tho, which, you can tell, is definitely further off than the above 479 one, tho:
278 Description said:
(2)-7-8 - The Aggressive 2
2-(7)-8 - The Power-Seeking 7
2-7-(8) - The Positive 8
"The Power-Seeking 7?" Nah way, dude. That ain't you. Not by a mile.
And, lastly, what does exist in the 279 description:
279 Description said:
279 Peacemaker Archetype
279
As a nine, I hate conflict. It's unbearbale when someone gives me the silent treatment, is angry or withdraws. Especially if I had a loving friendship before and when it hugely matters to me. I really like to bring things in the open and get things resolved. Talk things through. See where it went wrong. I do this without criticism. Though when somebody has hurt me and things have bottled up for a long time I can be very critical, precise and to the point. That's before a conversation to get things resolved where I couldn't control my outburst. Because it unsettles me and makes me sad. Then I can move forward again. When I try to discuss the situation I keep it light. Do not want to feel pain. I want things to be on the same level and harmonious as before and we do not need to delve deep, no need to dwell on the negatives. And let's forget about it. I will acknowledge my errors and empathise, even when I sometimes know I do this more then I should. I think the above is my 7 tritype. I think 4 is not the other tritype as I do not feel envious. It's not a passion or drive so to speak. Any input would be appreciated, thanks.
Have you ever taken the enneacards test on enneagram.net? It will help you identify your heart center, or at least give you somewhere to start.
From what you've described above I would guess you had 2 in the heart center, with two positive outlook types (2 and 7) and the 9 there is a need to keep things positive, a driving need almost or else it is unbearable. The criticality and bottling up phenomena could be due to the 9 in charge, and the 1 wing, as well as the social subtype who all are prone to a sort of indignant, critical anger.
Here's what Katherine wrote:
If you are a 279, you are caring, innovative and accepting. You want to be helpful, upbeat and peaceful. You are very kind and tend to see the best in others, focusing on easy and comfortable ways of relating. You hate conflict and/or strife and use your sense of humor to smooth out difficulties.
Your life mission is to create and promote smooth and harmonic ways to handle conflict. A true peacemaker, you are happiest when you can ease tension and help others get along with one another.
You can be so identified with keeping life free of conflict and negativity that you may turn a blind eye to conflicts that need to be managed as opportunities for change.
*Most optimistic tritypes-279, 729, 927
279...positive
This tritype [927] is the most identified with seeing themselves as peaceful. More than any other tritype, they need peace and positive relating to experience a sense of being... so are extremely uncomfortable with negativity in relationships. The 479 doesn't like it but expects it. It also brings the 937 tritype which is the true ambassador of goodwill.
If you have the sexual instinct as dominant you could easily identify with 974. The 972 is less ethereal and more focused on being positive. The 974 knows that they feel unhappy, they are more inclined to hide so that they will not be rejected for being negative.
The super positive types 279 and 379, report that they try to get thru grief as quickly as possible, especially if self-pres.
Yes, there is more than one positive Tritype. The super positive Tritypes are the 279, the 379. The 279 is a the Tritype that wants comfortable, easy relating. The 2 brings a greater emphasis on people.This is the 2ish caring, people oriented 7 or 9. The 379 is even more upbeat and positive. The 3 brings more of an emphasis on achievements. For example this is the professional, 3ish 9 or 7.
All of the 79 combinations are somewhat positive. The 279 is focused on being pleasant. The 379 the most positive. The 479 Is positive outwardly but doesn't always feel it.
2-7-9 - The Positivist
Characterized by unbridled optimism. They don't allow anything to get them down, and they love to enjoy themselves by surrounding themselves with great company and fun atmospheres. They may be a bit unrealistic however.
a person could be the 927 or "The Peacemaker" Tritype, and after utilizing the dominant Type 9 strategies the person may move to their lines of connection (Type 3 and Type 7) as well as to their possible wings (Type 1 and Type 8). However, if these connections are not effective for the person, they may move to Type 2 and become more helpful, effusive and relational, and then move subsequently to Type 7 to utilize positive reframing, escapism or future planning in order to achieve desirable results.

Trying to keep a positive outlook at all times. (9-2-7)
2-9s - They avoid admitting that they have a (completely) negative image (and avoid anything that may lead to such a state). They're ultimate fear is that they have a completely "black" image and are unable to escape it. They enter a strong state of denial when this occurs. This isn't necessarily because of the Two side, but much rather because the 9 side can't handle such a reality and thus this kind of Two is more likely to withdraw into a more "positive" perspective of themselves. It's much nicer and much more comforting that way.
"Positive, positive, positive. Optimistic, upbeat, positive."
If there's anything I associate with you, and have ever since I've been here, it's those qualities.
You are just a super upbeat, positive, optimistic person, who doesn't want conflict to be happening (but also won't necessarily shy away from it if it's sorta forced on your doorstep [which is why I definitely see 9w8 >> 8w9 [and 8w7 just isn't even a realistic option]).
So, yeah, I guess that's more than I was expecting to write.
And, after doing it, I probably feel pretty confident, actually, in 729/792.
Paraphrasing Nietzsche (cuz I can never find the quote): always trust your initial instinct.
