My '83 Catalina 36 has a double reef setup, (ending at the mast). The lines are huge, 5/8s or bigger, and thus heavy. In light air they drag the back of the sail down. And when the sail comes down, I have all this heavy line spread everywhere. So I'm thinking of replacing them with new lighter and stronger tech, such as Dyneema. Aside from cost, would there be any downside to such a change, any reason not to do that?
