LaPorta or Barton in a Dynasty? WHIR

[curl]

I'm in a deep 20 team, 25 keeper dynasty league. Categories are the standard 5x5 plus OPS and holds.

My 1B is rather weak. I'm currently playing Sandoval there, with Uribe at 3B, but I'd rather move Sandoval there. I was hoping one of 3 busts would step up this season out of Matt LaPorta, Brandon Wood, and Chris Davis for one of my corner infield spots, but obviously it hasn't worked out that way.

So would you move LaPorta for Barton? Or do you think it's too soon to try to dump LaPorta?
