if you guys use a radio to let your girl to stop fidgeting so much, or to start leaning more, what do you use? we'll both have full face helmets so we wont have to worry so much about wind noise. i'm just looking for something fairly simple that doesnt cost a shitload that'll let us talk. and when she's not on, i can hook it up to an ipod or something. anyone know of any good products?
