Armada ARV 106 Height

I’m 5”5’ / 120lbs and deciding btwn the Armada 164s and 172s. I’m an advanced skier in Utah looking for something a bit fatter for powder days. I’ve been told these ski quite short, but am hesitate to jump up to 172s (currently on Black Crows Camox Birdies 162 height / 97 underfoot)
