Replying to Extra waist width in the park?

I'm just curious about this. I'm currently on a ski with an 82mm waist and for some reason I've been really interested in wider skis like the nordica soul rider and the line blend. Does anyone have anything to say about how a wider ski acts in the park in terms of swing weight and just overall ability. I'm just wondering if it even effects anything because guys like huele and mcvay absolutely kill it on these things
