Less drag for more area, higher up => better lift/drag ratio. A sail that is in my opinion easier to handle and sail well with.

The "automatic gust response" is fiddly to get right and depends on a lot of variables. That is not the main point. A more efficient and userfriendly sail is.

am just graduating form mosquito catamaran to a stingray caamaran.


I dont knof if there is such a thing as "graduating" from mozzies. Seems like there is a lot of skill and experience in those fleets.
