that thing actually works? i have a quad fish and a thruster but would think in a good size hollow point that requires a real bottom turn it would spin out. yes I am sure kelly slater can surf a cooler lid in jaws but I got rid of my quad thing sucked spun out everytime waves got big and I cant see a tiny quarter inch insert making a huge difference. anyone ever surfed it in legit overhead point style waves? head high is good with a fish too. a few feet overhead and hollow is different.
