Pretty simple, really. In 2016 when I bought my 2016 GT 215, I was told the only way to screw-up the warranty was 1. Not take it in for service at the appropriate intervals and 2. Adding anything aftermarket. ANYTHING.
So I'm keeping my ski all original for two years. Then going nuts on it.
Fair trade off to enure my ski is in good condition before I start modding her.
