Replying to 06 /05 ski question

I have owned dynastar skis for a while. I really liked my candides and decided to buy the trouble makers afterwards. I really like the way they ski but I have issues with their durability. I blew out edges on both pairs of skis. I am tempted to buy the new troublemakers but I am hesitant because of my past experiences. Does anyone no of a twin tip that is durable and performs as well as the tms. How do the PES and Karmas compare. Any advice?
