Replying to Vishnu Wide+ For Big Mountain/Pow

I've been rocking Vishnu Wet+ the last two years and love em, best park skis I've ever owned. I'm now looking for a do it all ski to take with me on trips out west. This pair's main focus would be bigger mountain lines/pow skiing and such, with park thrown in here and there. I know what Vs are like in the park, but how do the wides perform in big mountain situations/pow days? Since I already have Wet+ would I be better off going for a dedicated all mountain ski? Or would the wide allow me to ride Vs on the gnarlier stuff as well? Lemme know what you guys think.
