Open limp with monsters?

[jakbse]

I'm a 16/8/1,5 player at party 0,5/1. The typical table shows VP$IP of 20% and PFR of about 6%.
Now, every time I open limp from EP with AA and KK it seems to blow the field away, often ending up with a blind steal. This would be fine for the weaker raising hands like TT and KQ but for the monsters it would be nice with some more action. I re-read the preflop chapter of SSH last night and it doesn't really touch this matter. Another benefit of not open raising is of course that you don't give your hand away. Any ideas of how to act with respect to various kinds of tables?
