Probably a dumb question, but...have you ever considered just picking up a 2X12 to go with your head? You already have the expensive portion covered (head unit). A head and 2X12 isn't much more than a 2X12 combo to lug around, it breaks up the weight for you, and it's a lot less expensive to add a 2X12 than a high end combo. Just a thought. I have a 1X12 I carry around for jamming at home or at someones place when I don't need one of my 4X12s for a full scale jam or show.
