I don't play high limit or anything, but I almost never reraise with aces unless I have one opponent and I can 75% or more of his or my chip stack in before the flop. Once you put in a reraise, most eveyone will know what you have, completely ruining any deceptive value you might have had if you had just called and taken a flop. Through my experience most of the hands where money goes in on the flop without aces hitting a set sees the aces losing to a flopped two pair or something of that sort. I feel its saved/made me a lot of money to flat call or put in an initial raise only with aces before the flop. Just my two cents.
