I'm considering a board made with Hydroflex "Natural" construction (epoxy over poly foam). However, it worries me that I've heard it called "extremely light", compared to standard 100% poly boards.

I've owned a few eps/epoxy boards and hated the lack of momentum that comes with ultralight boards. I've also owned poly boards that were too heavy and they sucked just as bad as eps. There's an ideal weight balance on the best boards of any construction - as far as standard shortboards go, if it has to lean either way, I prefer them slightly on the heavier side.

Is Hydroflex "natural" closer in weight to 100% PU or is it closer to eps boards?
