I am about a 1500 and am wondering what opening system i should play.  If it helps I will list the openings I currently play.  I play Queens gambit, pirc, and KID.  I am considering switching from the queens gambit as there is lots of theory involved and I am not able to get the type of position i like all the time (depending on which defense black chooses).  Any suggestions on which of these three systems i should play?  Thanks for the help!!!

Entirely a matter of taste.  Personally I have always found the idea of a one size fits all opening a bit distressing, but they limit the amount of study for sure.
