The wires have a maximum weight rating of approximately 13 grams per inch (or 82 grams per 6" wire) resulting in some deflection of the wire.
For little to no deflection, the wires should carry no more than 3.5 grams per inch (or 20.75 grams per 6" wire).
For best results distribute weight evenly across the wire.
All values have been tested at cone 6, results at higher cones may vary.
