Does anyone know what the difference is in the top slot heights of these 2 seats? I've replaced one of my sons 2 nearly outgrown Triumphs with a Radian but I'm wondering if it's worth it to get another Radian or if I should save $70 and get the Triumph Advance. He's very skinny so it's doubtful he'll ever outgrow any seat by weight.
