Looking for a board for my daughter. She is 7 years old, about 54" tall and weighs about 55 pounds. She has never ridden before. I am looking a several boards, most are either 109 or 119. Do you guys think there would be much difference in these sizes for her? Leaning towards the 109 because I think it will be easier for her to learn on, but dont want her to outgrow it to fast.
