Not at all, it would just be funny if you changed your opinion of my etype yet again. That would make you about as indecisive on my type as I used to be.
My type: SEI
- M&O subtypes -> Si-SEI
- Gulenko accepting/producing subtypes -> Fe-SEI
- Gulenko's DCNH subtypes -> C-SEI -> More "Creative" in the sense of being mobilised to resolve a crisis than enacting long-term fixes/solutions. -> Se-SEI.
So I'm really saying I'm a C-SEI, but for people who buy into the whole 8-subtypes thing, I think I'd be Se sub.

Anyway, as for tritype, I think it's a little divorced from the Enneagream, and should be more treated as a cousin than a descendant, despite functioning (or being billed as functioning) as an extension.
To be more clear, your core/base type, as you say, describes how you work on the inside, while the other two types from your tritype describe how you present externally, and your "next line" of defence when your main type doesn't have a response (which is nonsense... your main type always has a response).
For example, I'm 9-4-7. That doesn't mean I take the Holy Idea of each type, or anything more than outward behaviours. To some degree the 4- and 7-fixes can arguably colour my personality, and it seems like this or a related idea is what Dreamz was working from. Going with the stress idea above, I supposedly, under a lot of stress, relay my stresses on to my 4-fix for resolution (I'll write short stories, or poems, and get really withdrawn and broody and generally melancholy), then, under even
more stress, I tap my 7-fix on the shoulder and go "Aight buddy, you sort this mess out". That's typically when I fill up on some sort of stimulant and deliberately abuse my body and start hurtling into as much mindless activity as I can to keep myself distracted from the slings and arrows of outrageous fortune.
The other side of that is, according to the theory, I look 4-like and 7-like (but not 9-like... there's no such thing, lol) on the outside, I guess in the sense that I appear mixed very introverted, but with a charming, friendly, almost "extroverted" persona, or something; but I neither understand this aspect, nor do I have any real or substantial sense of how I come across to others (lol, Nines).
I mean to be perfectly honest, that all said, I can quite easily wrap up all the 4 and 7 behaviour into things that are perfectly consistent with being a Nine, and a sexual Nine at that (or more specifically sx/sp, I guess), but I like both having labels attached to myself and doing the same thing that everyone else is to avoid standing out too much.
