I don't knwo where this "Ledge" buiness came from, but I definatly demo-ed the Bridge. And they're the fatter ones, so the replacement for the Karma I believe. But they did seem fatter then the Karma, so I'm not really sure. It felt like I hadmore float and stability with them then on my old Scratch B.C.'s. So I'm not exactly sure what's going on, we'll have to wait and see, but I really liked the Bridge, and I wish I had teh chance to use them in a fair amount of snow, cause they felt liek they'd be happy there.
