I can't give you 7w6, but I can give you 7 and the stackings, from ocean-moonshine.net:
Social/Sexual
This Seven has a lot of energy although not always a productive energy, as it often contains a frenetic quality. These Sevens usually have a great sense of humor and many comedians are soc/sexual sevens. The social and sexual instincts go hand in hand with the type Seven fixation. These Sevens want to keep things light. They have fast sharp minds that incorporate social awareness into their humor which they use to get by in their interactions with the world. On the down side, commitment is a big issue for this subtype. They cultivate many friendships and can thrive on winning people over, making them laugh and entertaining them but intimacy can feel threatening and constraining. For others, interacting with this subtype of Seven can feel draining, because they are “on†so much of the time.
With the self-pres instinct least developed in the stacking, they tend to lose focus on their many plans. On the down side, their health and commitments can fall by the wayside in lieu of the buzz of the newest excitement.
In intimate relationships, this subtype is “the charmer,†but they maintain their freedom from any strong ties to the one person. They may end up in marriages or long term commitments where they hook up with someone reliable and stable, someone with a much more low key personality. This gives them the stability they don’t have themselves. This eventually leads to trouble if the soc/sexual seven doesn’t realize that responsibility for his or her own life can’t be transferred to another. It’s not that the soc/sexual goes into the relationship with this kind of pattern in mind. It is just easy for the dynamic to default to that dynamic.
Sexual/Social
This subtype has a lot of energy, crazy, intense energy and this energy is going to find a way to manifest. This subtype of Seven can have the biggest extremes in behavior and with material success in life. With the self-pres instinct last in the stacking they aren’t afraid of taking risks, so they sometimes become very successful, as in the case of rock stars, but they typically also take too many risks, look for too many easy ways out. With the self-pres least developed, they can become dependent on others to add a much needed stabilizing element to their busy hedonistic lives. They have many of the same issues and share many of the same problems as the other sexual first subtype with regards to relationship addiction and have even more dependency issues then the sexual/self-pres. They can lose focus and drift similar to the social/sexual subtype and their high energy can likewise be draining for others.
With this subtype, you have drama mixed with mental energy. What separates them from Fours who they might resemble superficially is their planning and future orientation. Their drama and intensity is focused on what they are going to do, not on what has happened. They are usually blind to their past, moving forward and not looking back.

I think in general when considering so versus sx, so prefers to expand to the greater arena. They feel confined by relating to only one thing for too long. Sx would prefer to relate to one thing for as long as possible. We sometimes feel pressured and annoyed by the greater arena for drawing us out of our immersive relationships.
