I have tried the 8,0 with the 90 %Duotone SDM and 90 % Ezzy RDM 460's ,RDM is better ,it seems to be able to get more belly in it with the RDM ,so better bottom end ,it feels a lot different to my 2016 and 2018 models ,Faster .and seems to handle more wind so stability seems better ,it really has surprised me .Being a custom the materials are slightly different and very good quality .With the new window you can almost feel a more positive feel out of the sail ,very locked in .stoked .it almost feels like it has a larger luff pocket ,almost like a race sail

rotation on both mast where excellent and that normal thump as is locks in after the Gybe ready for your next run .Had the isonic tail walking the other day .the idea of taking 2 sails and one mast 8,0 and 7,0 lions on holidays is now a reality
