I'm very happy with my Naish Jet foil set up.. and the adracadabra set up is awesome..
Especially for those long walks from your car to the beach.. or when carrying the whole thing through narrow pathways or steps.
The weight is not really an issue once in the water and foiling.. Those weights quoted above might change with different mast lengths.
I'd rather slightly heavier and strong than light weight and easily damaged.. The Naish stuff is pretty bomb proof..
