Should I always use a double wired cable on the new dynamo hubs?

Basically it is not necessary, but we strongly recommend it.
Because the paint quality of many modern bicycles is becoming better, it is more difficult to get a ground (mass) contact at the fork. Also corrosion between the fork and the hub will have no influence if you use a double wired cable.
So if you would like to have a failproof lighting system, you better use a double wired cable.
