Replying to Volkl Wall lengths (177 +185) vs. K2 measurements...

Looking at picking up some Volkl Walls.  The only ones left in stock at local shop are the 177s.  anyone know how Volkl measures their skis compared to K2 or other manufacturers?

I've been riding 179 K2s in the past and they are right on the borderline of being too short.  If the 177 Volkls are close to that, it's probably fine, but since Volkl also offers 185s I'm trying to figure out if the 177 are measured shorter (i.e. they would be the same as a 172-174 K2).

Any experience?
