I've since refined my enneagram as far as I really can go with it.
1w2 sx/so/sp
I am without a shadow of a doubt, a 1. There is no question on the matter! I have run the gambit with all of the styles that ones can enter depending on stress levels and have experienced what it's like. I disintegrate to a 4 in a bad way, and my wing distintegrates to an 8 in a bad way. Not a pretty combo. In particular when I am taking it out on something without knowing it. When I develop I integrate to a 7 and my wing intergrates to 4. It's so... refreshing! Interestingly, my stacking doesn't factor for me much. There is an order to mine for sure, I am sx/so. That being said, my sx is not overpowering, and my sp is not weak. There all close to each other.
If you follow the tritype theory I am 1w2>2w1>6w5. However, in terms of understanding myself and how I behave in and out of stress, this simply acts as a mild refining tool. Most things can be reasoned inside the 1w2 bubble.
Yay enneagram!
