this past year i was 5 foot 5 inches, 110 pounds on a good day. i got 166 ar6's and they were over my head and i was freaking out thinking they were too big and too stiff...I actually made multiple threads on it seeing what i should do with the skis (i was a nag, ill be honest)
...turned out after the second time down the mountain, i loved them. they felt perfect. as the season went on, they started falling apart..i actually found myself wanting a stiffer ski. So i found a good deal on 161 suspects. They felt amazing and actually held up way better than my armadas so far. i liked the stiffness (no homo) ..but i liked the 166 length better.
moral of the story, sack the fuck up, and buy some skis that actually fit. for you, buy some 161 atomic punx. they'd be perfect. dont buy some kiddy ski, they arent made as well (not up to par with durability of "adult" skis) .
youll probably start to grow some too, so dont be afraid of the 161!
