I'm a 54 yr. old die hard skier, powder lover & volunteer patroller. Looking for the one boot quiver for mountain skiing, sidecountry powder & all day in boots patrolling. spent 3 days hiking & skiing at Silverton in March and would've liked the walk feature, sole & some more shock absorption.. any advice on these 3 boots or does it come down to what fits best? currently in Tecnica Diablo Fires so will be a new shell no matter what. Thanks much!
