Winterberg (pps) At the Viessmann Luge World Cup in Winterberg last year the Italian luge team had left its mark. The protégés of head coach Walter Plaikner celebrated two victories - with Armin Zoeggeler the winner in the men's singles as well as Christian Oberstolz-Patrick Gruber in the double-seater. Winner in the women's singles was Germany's Natalie Geisenberger who, at that time, celebrated the first of her so far four Viessmann Luge World Cup victories in Winterberg last year.
