I'm seeing a lot of younger skiers with the reflex hard shell and rear kicker setup or "some other boot" & rear kicker. One of our better younger skiers was openly talking about switching back from double boots based on his observations that the a lot of the top skiers are using kickers and that allows them greater freedom to move on the ski... I'm a double boot skier and would not personally entertain the thought of a kicker but I have to acknowledge at our last tournament the vast majority of the 60 plus skiers were using them.
