It is not only Gong that has the LE blow up issues, Cabrinha Crosswings got it too, and seen on other brands also.
But it is not because of a roll in the surf, which they should be able to, it is most likely manufacturing defects.
Or it could be some kind of harsh toll when they slam into the surface on the leash, when learning in particular, which is harder than we think.
Most likely a combination of both
The major hazard is the foil killing the wing, when rolling/flipping, has happened to many, and just "how it is", nothing you can do about it.
Get it repaired, it will happen for some, now and then.
Luckily wings are quite low cost compared to other "wind" gear as windsurf rigs or kites
Major pain is being without the wing for a while, right?
