I bet more depending on position or how many limpers are in front of me, generally I raise less in EP and more in LP and more when there are limpers in front of me. At the micro level though, I always am gonna raise for at least 6bb with AA, KK or QQ. The higher the stakes you may want to mix it up and raise suited connectors to keep your opponents guessing. When I limp I usually do so with Axs, suited connects, or low/mid pocket pairs. It's hard to give guidlines exactly how much to raise because it really depends on the table (loose/tight) and if you raise the different amounts for different hands all the time you can become predictable to attentive opponents.
