Welcome to our new beta design! Click here to go back to the old Newschoolers.
onenerdykidThe Warden is a binding that is designed to be used if you have multiple types of boots with different sole norms (i.e. Alpine sole, Touring sole, or WTR sole). It is for sure strong enough to handle the skiing you will be doing, but (given how you described your needs) I would think that you would be better off with an STH2 13 instead.
But, if you were to go with the Warden, it will be fine. It will just have features/adjustments that you may not want/need.
