Merlin's performances were subsequently rather inconsistent, which is why the coaches often relegated her to the European Cup. It was not until December 1997 that she made it into the top ten in a World Cup race. The only podium was achieved on December 19, 1999 at the Super-G in St. Moritz , where she was second behind Karen Putzer .
She competed in the last World Cup race in December 2001. Two years later she took part in the Winter Universiade in Tarvisio and won the Super G gold medal. Merlin has been competing almost exclusively in carving races since 2002 . In the FIS Carving Cup she established herself as a serial winner: She won more than 25 races and won the overall standings in the winters 2002/03, 2004/05, 2005/06, 2006/07 and 2008/09.
