This is another debate that will run a nd run. Just checked boards Forum to see what opinion was on there. Rik (of Rik`s Windsurfing) posted this;

Like with so many things it’s all rather subjective to the user, the conditions they sail in and the equipment combinations being used. I know many sailors swear by the softer more forgiving flex the RDM provides but that is often making up for other deficiencies (technique or equipment set-up). In general terms however, easier conditions that do not require the extra strength of the RDM benefit from the extra power and wind range offered by the SDM. "

Best regards,

This is the NP line on issue. I use NP sails ...nufsaid.
