Check out the below link from last season. I opened that thread following a demo day, and, thought the 81 was the best ski I tried that day at my small home mountain in Pa. where short skis and hard snow rule.
Volkl has changed both the 81 and 84 for 2016 to put more camber into the ski. The initial reviews indicate the newer model is superior. I would think that any on-line deals are for the '15 mode. My first thought is they are too much ski for an intermediate, especially if you are skiing slowly. They are serious carvers, somewhat heavy. At your weight, you would need a short length. Yes, they will handle light snow, but, so will almost any ski. In mogules, it's a lot more about the skier than the ski, but, they would not be my first choice if I skied a lot of bumps.
Try them if you can find a demo, but, I would advise finding a softer flexing ski to develop skills.
