Mid pocket pairs in EP in middle levels

[The Deuce]

I apologize for the noobish post.

Basically I'm unsure of how to play 66-99 in early position, with middle sized blinds, a stack of between 11 and 15 big blinds, and 7-9 players. For example, in the Party 50-5, say I'm UTG with 77, 1100 in my stack, blinds 50/100, 9 players. I always feel uncertain of the proper play. Raising is uncomfortable, limping isn't much better, and folding feels a bit weak, although less so with 66 obviously. How do you generally approach the situation? Thanks in advance to anyone kind enough to indulge me in this rookie inquiry.
