Hey mate
friend of mine went libtech a couple of years ago, aiming to trial durability for that surf/kite cross over type board (as we all do at some stage with mixed but usually little success

)
he did kite it (different model to the RNF) ok, but was being pretty conservative at the time.
funnily enough, creased it surfing pretty small local (Perth) shore breaks instead, and it was a write off. Disappointed with that and he didn't go back.
Just one experience so take it for what it's worth.
Agree with above that the RNF has the right ingredients in the mix etc
cheers
