Playing pairs in single table tourneys

[cavalier]

I am never sure how to play a small/medium pair in a sit-n-go tourney. I'm calling 2-6 small and 7-10 medium.

I would think the strategy is different when there are 6-10 players and 2-5 players, but I'm not exactly sure if I should be limping in, raising, or what.

Any help would be appreciated since I'm pretty sure I'm missing out on lots of profit with these hands.
