Yo mang, I'm 4'10" and I just got the 190 Level 1/Moment Bibby Pro cause' they're super dope looking and are perfect cause' bigger skis make you look cooler. Plus they're just super steezy and hyphy looking.
But seriously, you should be fine. Volkl measures small, so in reality it's about the same size as a 161 line ski or something comparable, you should size up if you want a true 169.
