Listen carefully to what JD says at the end - monofilm sails were as crisp and strecthless as it gets although lasting 5 minutes. This why there is no substitute for monofilm in race sails for the time being. Reading behind the lines means that carbon laminates maybe lighter and bells and whistles in the beginning, but over time strecth. If you buy a 150 cm wave sails after using it 20 times it ends up 154 cm which might not be bothering fore some people despite spending a fortune.
