Replying to Skis wide enough?

I am rocking the 2019 K2 Sights at the moment. I ski a small resort in Ontario with a significant amount of hard packed snow and ice. I feel like the 88mm waist of the sight is ideal for these conditions, or would something like the poacher be better?

I travel once or twice a year to a large resort with deeper snow, would it be worth upgrading for this? The sight has a nice amount of rocker in the tip and tail, would I get a bit of float out of them?

I also teach in these skis and I feel like it might be easier in a narrow ski. Let me know what you guys think.

thanks guys
