My relationship with my integration point is interesting, because not only is it also in my tritype, but it is VERY highly developed in my tritype, to the point that some forum members think I'm a closet 7.
What I like about it, is that it calms down my 1 standards. It doesn't lower those standards, but it keeps me from suffocating under the weight of my own moral code. What I don't like about it is that it makes me far more easily distracted than I should be. Less productive, less willing to complete tasks that aren't "fun".
As for 7s themselves: I like them. They're fun and refreshing and balance me out well. I think I get along naturally well with people who have 7 somewhere in their tritype -- though probably better with people who are 7 second or third, and not first.
