Anyone used a Neil Pryde Flight Evo 3 and can advise if its any good for course racing compared to the Severne HGO's?

Only 9.0 is suitable for CR. Flight II all sizes 8,0 9,0 and 10,0 are pure CR sails !!

Thank you. Is that the same for Flight Evo 3?

I saw a video with Nico Prien where he and someone else were talking about the Flight Evo 3 and they said the 7.8 had leech flap so they fixed that for the Flight Evo 4.
