The point was made that the chips falling out and wearing badly has been highly improved by the "chip keeper" design. We really don't want to get into a discussion about making major changes to the design though. That is a hornets nest. Basically, the boat is intended to be one design. That means you change as little as possible. Just changing the cup to a ball on a post changes the goemetry of the rig by placing the pivot point higher. That there is enough to nix the idea.
