Replying to Kung Fujas - 179 or 189? FKS or Schizo?

I'm 6' tall and 140lbs and I'm going to get the Kung Fujas at the end of this season, but I'm kinda stumped on what size to get.  I'm aware the k2s run a little longer than advertised, but I'm not sure if the 189s would be to much ski for me or not.  I don't ski all to much park, but I prefer an almost symmetrical ski with a modern mount, so I don't think the Kung Fujas will disappoint me. Any suggestions would be appreciated. 

I'm also debating between the Marker Griffon Schizos and the Rossi FKS 140s for the Kung Fujas.  They are the same price and I like the idea behind the Schizos, however I know that the Rossi FKS is a great binding that will not disappoint me.  What do you think?
