Nordica Dobermann Spitfire (black top) 170cm from last year.
Ski chatters on steep, firmly groomed trails. Works well in medium radius turns on flatter terrain.
Went back to my old skis (178cm Volant Supercarve Legends) with no chatter on the same trail, same day. Also my other Nordica skis which are softer and got more chatter with them too.
Trying to figure out what about the design of the Nordica causes the chattering...
Maybe too soft torsionally and the skis breaking loose?
