Backcountry Ski Recommandation required

Hi,

I am just looking after Voelkl Gotama skis. I know there are a lot of other
good skies for backcountry and freeride purposes. I need some advice and
explanations what kind of freeride ski would be better and what are the
differences.

I saw different models from K2, Dynastar, Head, etc.

Currentyl I have a Head Monster with the following cut 116/75/101. I love
this ski for riding slopes and ungroomed terrain, but backcountry is a
different subject.

Thanks in advance. Regards, Matt
