Replying to Kartel 98 or 108 - Cant Decide!

Background - I'm 5'9 170 lbs. I am an intermediate to advanced skier. I only ski 1-3 trips per year and I always go to the rockies, typically Colorado. I am looking for a one ski quiver to take all mountain. I primarily ski ungroomed blacks, trees and bowls and occasionally take a park lap but not often. I spend more time than I would like on blue groomers but I want a ski that would make me more confident / better in bowls and steeps. I also want to be able to jump and butter so that is why I am looking at the Kartel series. I have never skied a ski wider than 90 underfoot so the 108 seems like a big jump but would the 108 be the better choice for me? I will be going to Jackson Hole, Breckenridge and Whistler this winter. Any advice would be appreciated!
