I LIMP with anything from 10-10 to 2-2. If one overcard hits the flop, you could be beat. You can't really call big re-raises preflop with very low pocket pairs. Also, you must remember that there aer only two other cards in the deck that will give you a set, not the greatest odds
... I like when players play low pocket pairs against me and keep betting, especially when i have hit my pairs with overcards. Most of the time, I throw my low pockets (55-22) away if there is a raise in front of me preflop. If players push all in preflop, I'm only calling with AA to 10-10. And only with 10-10 and JJ if I have a much larger stack.
