Replying to Nordica Soul Riders for Park

Thinking about getting a pair of these. I ski almost all park with the exception of a few days out west each year. Im currently on 176 Thall's but would like a ski with rocker and a little wider. These seem to fit the bill however I'm wondering if 98 underfoot is a little too wide. Anyone ride these that could give me an idea how they perform on jumps and jibs as well as all mountain? Is a wide ski noticeably heavier than something narrow. (I figured I'd get used to it and adjust after a few days) I'm about 5' 9" so I'd most likely get the 185's since I've heard they measure short. Any input is appreciated!
-Thanks
