AJo from MP, basic question

Typical low limit game. Few fish, few rocks, few better than average players. 10 handed and Im in MP1. First 3 all limp in. I raised holding AJo.

This is usually a hand that plays best vs small field and Im the 4th one in. Should I have just limped?

Not only should you raise for value another reason for raising is not letting the blinds have a free ride to seeing the flop as well as the possibility of buying the button for the later rounds of betting.
