Setting up Canti Brakes with Shimano 105 5700 STI's in the front

See how your outer visible in the picture has a slight kink in it before it goes in the guide? Ideally you don't want that, you want the smoothest route, whilst allowing a full rotation of the bars in both directions. If you use a front hanger - (like this http://www.edinburghbicycle.com/products/tektro-fork-mount-cable-hanger?gclid=CJTqsdqkyr4CFWqWtAodnVwAHA) that might help - it'll also reduce judder from the brake

Thanks mate -
Do I use that front hanger with the current hanger I've got on the headset? or is it an either or?
