Looking for fun skis to do more powder to the side of the piste

So I'm looking for a second pair of skis to do more powder and side hits. Right now I have Rossignol Hero Elite ST Ti's and I feel like that they are purely for on piste skiing and are quite difficult to use in other conditions. I was eyeing the Salomon Qst 92's, but I have no idea if that's a wide enough underfoot for skiing powder? Or should I lean more into some more wide skis e.g. Rossignol Super Blackop 98's? What are some good skis you guys suggest? Thx!

Ps.: I only ski in the Alps (I don't know if that's an important detail?)
