How important is the girlfriend on the back? If it's very important, she's going to be happier on the Versys. I haven't ridden the current ZX6, but had one a few years ago and my wife wouldn't do more than 20 miles on the damn thing. If it's less important and handling takes precedence over comfort, the get the ZX6. If it was me I'd rather commute on the Versys. The other option is to swindle your friend out of the Benelli and ride that, sweet bike.
