First off, i have no experience with the AR6's but have owned 2 pairs of chronics over the years, very very fun ski for park but it will have a fair share of top sheet chipping, like any ski. What i really like about my chronics is how they handle outside the park, in addition to all of its park capabilities it is a great all mountain jibbing ski, very responsive and poppy.
Lastly, it is a great ski for linking turns on groomers, i love how well this ski handles groomers, they transfer so well edge to edge that its enjoyable to make some turns on those days when im just cruising around.
