So I am looking to get into SG skiing next year. However, I thought It might be a good idea to get the skis this year as I am not likely to grow taller, only a little heavier. ( I am 14 and am 5' 10", 130 lbs.) If I get them I am planning to free ski on them this year in order to get used to them (obviously safely, on a non crowded day with nice conditions) and then race SG on them next year. Is this advisable? If so, what length/turn radius should they be? I was unable to find a sizing guide for SG skis online, so recommendations from you guys would be great.
