If you're in a LTR, what are some things to remember (to maintain frame) when meeting the girl's closest friends for the first time?

Obviously, a LTR is a balancing act between alpha/beta traits. But I'm not sure how to play it in this instance.

I'm not sure if it's better to show off my mature, caring side or to show off my "fuckboy" side. I can see that they would both have benefits. If I show off my beta qualities (without being a doormat), her friends will be impressed with me and tell her that they like me (upping my value). If I show off my alpha qualities, her friends will probably get their panties wet and that again will up my value.

Advice?
