ENTPs test as:
7w6 3w4 6w7 7w8
7w6 is the most common, followed by 3w4. Well, I actually test as both, in different times of the year.
8 is more ENTJ...but I'm not so sure about that.
There was this graphic in a previous thread about how ennneagram types are distributed along the MBTI types...I think highlander posted it.
