First off, hi all this is my first post. Second, here are the answers to the 5 questions:
1. We ski in southern Ontario with once a year trip to northern NY, so far all to whiteface in Lake Placid.
2. We ski mostly groomed runs.
3. We ski about 8-10 days a year
4. She is intermediate after 4 years of skiing (recently transitioned from some slide slipping between linked parallel turns on steeper slopes to properly linking parallel turns)
5. Height 5'4" weight 156lb.
Last year she skied on 130cm skis which were on the short side for her but I figured they were good enough to get through the season, which we got as a half back at a local ski shop. This year the shop did not have anything in her size so I monitored craigslist/kijijji for sales as I do not want to buy new while she is growing. Anyway to make a long story short nothing came up so we went to a play it again sports and picked up a 163cm Head Hot Thang with Tyrolia RFD 11 bindings which I know is longer than recommended however she is still growing fast and I figured she will grow into them and they would last a few years. A bit of frustration of not finding anything played a role in going for these as well.
Based on what I have been told at other ski shops and looking on line the commonly recommended length for her would be about 148-150cm. Interestingly enough I noticed that on this site the recommendation is 151-175lb = 160cm which would make them slightly longer which I don't think is a big deal.
So my question is, is 3-10cm longer than recommended length a bad idea or should she be okay with them? I looked up reviews on the ski and I thought they would be a perfect match for her in terms of flexibility and short turn radius (14 IIRC) which would compensate for the extra length as from what I understand it's harder to exit a turn with longer skis. The reviews indicate these skis are light weight, turn easy and ideal for someone under 200lbs.
Now that I bought them she will try them and I hope she won't get frustrated with them. I guess ultimately I'm just looking for reassurance that I haven't made a really bad decision in getting them.
