Snowboards

Four specs tell you most of what a board will feel like: shape (true twin rides the same both ways; directional boards have a dedicated nose), profile (camber is poppy and precise, rocker is loose and forgiving, hybrids mix the two), flex (1 is noodle-soft, 10 is race-plank stiff), and effective edge (more edge on snow means more grip and stability; less means quicker spins).
