The best thing you can do for your grom is get them dialed in on this wakeboard. The Fury is all about helping kids progress and improve their riding. As they grow, the boards grow with them. The 115 a has mellow 3-stage rocker with a soft edge, the 120 features a more aggressive 3-stage rocker with a subtle sharpness to the edge, and the 125 has an aggressive rocker with a sharper edge for that larger wake. The Fury is the board of choice for young phenom Hudson Haynie. If this kid likes the board, every kid will like this board.
