Just look at the price of a UHM carbon mast, back in 2018 that would have bought you 3 complete foils. People will pay.
In my opinion.. Mast is not the same thing. If you want stiffness/thin you don't have any other alternative. However, numerous parawing options are available.
I can say that i would have considered acquired an Afterburner if it had been offered at a ok price.
