I've used them for sup surfing in Nosara Costa Rica. Gee wish I was back there right now escaping our winter
Great paddle, super light & you can generate great cadence easily.
With the Aussie dollar being the way it is, way too expensive to bring in from the states, would be over $700 AUD for the carbon models.
