Thanks for the feed back. Yup, if you're running at speed and you see Dad and his kiddos way up ahead, don't wait, brake now. Also as you noted they were not made to run flat on hard snow; keep them slightly on edge.
For sure and that's a great point to those that are considering buying these. While they aren't by any means super difficult or demanding skis, they absolutely require that you be skilled enough to use the edges of the skis and drive through the tongues of your boots. Another related point - those that ski in a more neutral (as opposed to forward) stance probably will not enjoy them.
