Giant Frisbee's have a rattle? I've never noticed on the NA models, one I literally rode Saturday. But I also didn't notice Banshee had one because I cared more about the giant amazing inversions than a slight shake.
And yeah, I need to go to Liseberg, my family has Gothenburg as one of the final contestants on where we go in Europe either this summer or early fall. But there is still London, Berlin, and Dublin and I've been vouching for Berlin and London.
