Foil only on warranty

Why foil only, if the hinge removes most of the strain on the tendon? Well, the tendon is shorter than a standard tendon. On the plus side, the universal is only 5/16” taller than a rubber universal and the bolt under the universal is centered. Decided to keep it because I am lighter and only sailing flat water, but may go all new rubber universals, to be safest.
