Keep in mind @Posaune did note he is a cheapskate (I say this as very much a cheapskate myself). Getting one ski on a screaming deal makes perfect sense; buying a new two-ski quiver, even with screaming deals does not,.
Not adding two skis to the quiver is just crazy talk.
108 mm wide suits me fine at 160 lbs for deep snow. OP's weight and the snowfall amounts where he skis cries out for wider skis, especially given his preference for the ungroomed loose stuff. The Pro would have less overlap and is designed for fast skiing, but beware, it might produce a new addict.
At the other end of the quiver there is nothing narrow. Maybe a race ski to play with for something different. Yeah, I know, why ski groomers when you have deep snow and trees to play with. Eventually you will explore all options. Why not now.
