Replying to Advice on a second ski for my quiver

Hello, I am going to be skiing in Colorado. I am 18, 145~150 lbs, and 5’9. I am an agressive skier and want a all around Powder ski. I already own a pair of 171 2016 Filthy Riches and want a pair of skis for powder days that still have some freestyle capability. My filthy riches are already pretty tall considering my height so I’m cautious about going much more than 171. I am looking at the kartel 108s and kartel 116s (but the shortest option for those are 176). Thank you for the advice in advance.
