Hi, I' m using a Black Project Hydro for several months. It's a high quality made, very light. The shape of the blade allow an easier catch and give an extra stability in the power phase during the stroke. I'm 70 kg and uses the hydro 78 with the soft shaft for all my sup sessions ( down winds, flat water, beach races...) and like it so much. ;-))
This is one those great paddle, it's well design, well made and light too. Like every paddle just make sure you get the right size blade for your height and weight. ex, I'm 80kg 5'6 and the 83sq blade is good size, the 88sq might be a bit big and 78sq is nice in the surf. You can get the blackproject gear at Core boardsports & SHQ.
