Normally medium pocket pairs I'd call 4-5x BB with the hope that if it hits the set I can double up. Now in the hand below I would normally fold to a 7 BB raise, however my reaction was more callers = more likely to take a stack if it lands. Now I'm wondering if I should consider more callers = more likely to be beaten even if it lands. Or just plain, too expensive to play in. Not sure how my thinking should go in this situation.
