Looks like the French Windmag have just put their test writeups online for all to see. Last time I looked they werent there.
www.windmag.com/voiles-2022-xo-sails-sharkThey test a 5.7m, not your sizes, but gives an impression.
RAS is an acronym for rien a signaler - nothing to report. Good to have that in the negatives in the summary.
I think they are made at the same loft as Simmer. Older XO sails were well made, but lacked the performance, so a friend sail who had one told me. I think they have put in a big effort in the last couple of years, with some collaboration with Simmer.
The XO masts are on the flexitop side of constant curve, like the Simmer masts.
I would be interested in your impressions, the Shark would be a sail I would go for, if I couldnt afford/get hold of Ezzy sails. They would probably be a decent fit on my Ezzy masts.
