So for instance, according to my theory:
-The 8w7(7w6) is ridiculously confrontational and also has a more head-centerish energy compared to the rest of the 8's. They are probably the most confrontational of all the 8's. They are also probably the most energetic. Think Tony Montana and think Tuco from "Breaking Bad".
-The 8w7(sw9w8) is also confrontational but sometimes they just let confrontation go because they just don't give a damn. Their energy is still somewhat fast paced, but slower and less flashy than the 8w7(sw7w6). They aren't really that head-center at all and come off as EXTREMELY gut-center. Think Tywin Lannister from "Game of Thrones".
-The 8w9(sw7w8) is more confrontational than the 8w7(sw9w8) but less confrontational than the 8w7(sw7w6). They tend to be the "tell it how it is" 8w9. They tend to be very brave and charismatic leaders and don't tend to hold back. Think Dr. Martin Luther King and Dr. Phil.
-The 8w9(sw9w1) is almost like a grizzly bear. They give off a "Don't mess with me" vibe, and you know not cross them, but they don't necessarily come off as scary as the other 8's. This is probably the most gut center of all the 8's. This 8 can sometimes be confused with a 9, because they often times will avoid confrontation if they don't view the other person as a threat. However, again, you still know not to mess with them. Good examples of this type of 8 are Mike from "Breaking Bad" and the guy with the burned face from "Game of Thrones".
