I have the earlier "tendon" style tiller connectors, one of which has already stripped out and been shortened by the previous owner. So it's time for an upgrade. The Wave upgrade kit "'07 Tiller Connector (1957)" looks slick and won't pinch my fingers.

The Hobie 20 system has rudder alignment adjustment for twice the price. So ... which one do I want? What are you using?
