She's already a ripper and deserves a real snowboard with some guts and pop. Get her the Burton Yeasayer Smalls Snowboard and rest assured it comes with all the features the adult version has, like a Super Fly 800G Core with Dualzone EGD (vertically laminated wood over the toe and heelside edges for better edgehold) as well as the Scoop nose and Pro-Tip construction for less swing weight. Burton keeps the Yeasayer Smalls maneuverable by building in a Flat Top rocker profile and dailing back the flex in the fore and aft section of the board with Filet-O-Flex (offers easier turn initiation and less hooking). All this and Burton quality, plus The Channel™ mounting system adds up to a win-win for you AND her.
