Replying to Kartel 98 or 108

I have been a long time lurker for a pair of ON3P’s but really struggling to decide whether the 98’s or 108’s are right for me. 5’ 10” 200lbs mostly Vermont skier with a couple trips out west. I ride all mountain. Love to rip down trails and explore the trees. I like to hit the park but lower on my agenda since I am getting older (27.) I am leaning towards the 98’s but unsure how they perform in powder. What would you do if you were me?
