WIll be getting those at some point on my bike, even with the low tier groupset (Veloce).
It's not going to work in a way that shimano would consider most efficient Ed .. When they moved the cables to be internally routed they upped the cable pull to the shifters and brakes to overcome the friction in the design. To offset that they increased the mechanical advantage in the brake. So you'll end up with a lever that goes to the bars and then the brake snatches on with nothing in between .. I would suggest ..
