This brand was tested on the North Shore of Hawaii and produced by John John Florence. Black 6 Standard Green 6 Super Comp The Green Super Comp has a thinner cord diameter than the regular Comp, making it effective in small waves. It had less water resistance and felt light. The black one was mainly used when the waves got bigger. Both were used for about a year. They show signs of use, but the Velcro is still strong, so I think they are still perfectly usable. Thank you for looking.
