Replying to Looking for a playful pow/all-mountain ski

I live in CO and I already have center-mount park skis and skis that can handle basic all-mountain (ie groomers and such).  I'm looking for a ski I can use mostly for pow but can hold it's own on all-mountain.  It would be nice to have it be soft, because although I like to charge, I want a fairly playful ski.  I was looking at the JPvsJulien and the Line Lizzies.  I've heard some people say the the lizzies tend to dive in powder, and I would get the SFB's, but I'm worried that at about 5'5" (will have grown a little bit by ski season) 182s might be a bit much for me.  This is also my concern on the JPvsJuliens, is 178 too long?  I do really like 08-09 JPs though...
Also, I am only like 110lbs (once again, probably a little bit more by the ski season), so something that's really stiff wouldn't be ideal...
