Does "Doudess" refer to the subtle bi-color design on the yellow rope? Is that worth an additional 45¢/m?
That is a center marking pattern. Half the rope is one pattern and the other is a different pattern. Yes it is worth the cost.
Duodess is not bi-color. It is Bi-pattern. The pattern changes at the middle. The difference is Bi-pattern they do not have to splice the sheath and on a bi color they do and it creates a bump the can wear funny at the change. And yes they actually splice the sheath yarns but not the cores of course to make a bi color rope.
