I never see people using powder cords anymore either. They are a hassle and have to be fiddled with every time you take your skis on or off, which is a lot when you are cat or heli skiing.
That said you never know what a released ski will do. In 2012 one of mine submarined under the powder for ~30 feet before coming to rest and leaving only a subtle disturbance on the surface which Mustang owner Nick spotted after half an hour of searching. Sometimes a fat ski will run down the hill on the surface for 200 feet or more as the ski brake doesn't have much effect in powder.
