How about occasionally limp/re-raising QQ+ from EP at a table where you are quite confident there will be a preflop raise? This is really for trapping, not range balancing.

Haven't done it myself very often, but it seems quite efficient.. Quite often the original raiser will stack off facing what he thinks is an "obvious bluff" or "another tilting donkey who overplays his small pairs".

Got caught by it myself several times...
