Living in the East on often hard snow and unpredictable conditions, the 165 cm slalom ski with a 12-13 meter radius is my go to ski. When I am coaching the kids, doing drills, and just free skiing you just can't beat real slalom skis for precision short turn skiing. I will even run a NASTAR type GS course on those skis with no problem up to say 16-20 meters. Slalom skis also work on really hard snow and bumps too. My favorite drill with the kids is to make lots of short turns on steep and bumpy terrain, as you just can't ski those conditions without a good pole plant. Watch Mikaela Shiffrin and she has a consistent pole touch on every slalom turn, especially when it's steep and icy.
