Final review on Kalliste...I managed to break the paddle blade in a rock garden while surfing. The foam core thing is too weak in our opinion. And even Werner warns that it can be stabbed through the glass face. So we got rid of the survivior and got Werner Camano bent-shaft carbon fiber paddles since we got a deal from NRS. AT was too expensive and cadence was too heavy and felt weird in the hand to us.Got out replacement Werner carbon bent-shaft Camano paddles at 230 cm. They're light and seem real strong. So far we've paddled only a 100 or so miles on them; 75% in semi-rough to rough open ocean, 25% in surf work (we're sea yakkers) and they feel and work well. We did notice the apparent seam in the shaft that was sanded smooth only at the joint and hand grip areas. AT and Cadence are perfectly finished compared to these. After a couple hundred miles and a kayak trip of two we'll post a followup review.
