It's OK. Compared to my Fargo, which was rock solid with any loading at any speed I could obtain, the CC has noticeably more shimmy if, for instance, I bang my hand on the handlebars. So the cure is not to do this. That being said, for the limited amount of loading touring I do, the CC is good enough, and the Fargo was too stiff to be enjoyable to ride unloaded (for me), so it's been sold.

I've never ridden a Double Cross, but from what I've read of comparisons between the two, I don't think it would be substantially different.

Maybe a Vaya? Especially if you want discs.
