I reckon it's amazing how much speed concaves generate. So good on small wave boards for instant speed. Makes em like a skateboard. That said I reckon slight vee is great for a step up board for good waves as you can really generate speed going from rail to rail.
Rant over.
I had a DHD quad that had deep double concaves through the fins, was awesome in small waves!!

That looks intriguing. How does it ride compared to standard double concave?
Probly similar with less bite and not as quik at a guess
