Replying to Are k2 seth vicious good for alaskan skiing?

Hi guys , i got a seriuìous question for everyone is a good backcountry skier.
I'm planning to go to Alaska for a few days.
I'm got a pair of K2 seth vicious 180.
My question is...do you think they can be a good ski for Alaska or should i consider to buy something different (stiffer) for that kind of
terrain?
I'm 5.8 height, 150 lbs weight.
Don't answer me that seth morrison use the same skis, 'couse I'm not so sure that seth has a standard ski, but like most of pro they have skis made just
for them.
Any help and advice qill be appreciated
