allin or fold

[Allinlife]

I'm very sorry, because this question probably has been answered before.

but what do you do with pocket pairs below 8 in following situation.
pp 10+1
4~5 people left
blinds are 50/100
you have 8 BB
chip leader with 25BB limps in UTG
mid stack with 15 BB limps in after
it's your talk and you are looking at 66
2 people after you (another shortstack and mid stack)

fold or allin?
or do you call for set

Ugh.. 8x BB, little folding equity, just good enough hand to move in. Fold, unless I have something on the other guys, but eh...
