Given the dificulty, cost, drag, durability, etc. of switching from wire to dyneema (or what have you) I wonder what is the benefit supposed to be?

Is this all just to reduce total weight on the boat? What about the wind drag of the fatter line vs. the skinny wire? Has anyone weighed their 3 wires (ok, 7 if you include both trap lines) vs. the lines? How much total weight savings is there?

Even most A cats are still using wires vs. line, at least for the rigging if not the trap wires too.
