All I can say is why have I been using a clunky carbon fiber euro paddle all this time? All of my kayaks (sea, tour, rec, fish) actually paddle faster and significantly easier with this carbon GL paddle. Shoulder stress? Gone. Rolling? Effortless. The technique is slightly different, but much more efficient! High quality. Very satisfied. I chose the shouldered version so I would always know how I was holding the paddle were when my attention was elsewhere. Highly recommended.
