anything will break over time... just some take longer then others.
One twintip for example only lasted a couple of months for a guy , but he is 200+ and like to ride powered 100% of the time .. he hucks it large and comes in hard. He split the board right under his boot. Another guy is 200+ and hucks it just as large and comes in smooth and has been riding it for 3 years now.
Surfboard built one that has lasted a teamrider for 3 years now and still looks like new. he does strapless airs all the time. not even a heal dent, ( heavier then a production board but built to last) he has a production board not even a year old and it is dented all the hell and taking on water.
Bottom line is how you look after things and how you ride.
I am sure Carafino foils and board are great and will last a life time if you look after it. If you are jumping 30+ feet with a foil sometime will break sooner or later.
just my 2 cents
