Default Formula Fin Stress Marks


I have an F161, with the stock Drake 70 cm fin, which I sail recreationally. I'm concerned with the durability of the fin, since both sides are showing a white stress line along the base, one side isn't bad, but the other is a very pronounced white line. Is the fin in danger of breaking? It's not that old, and not that heavily used. Are there other fins out there that last longer, that I don't have to worry about them breaking?
