The 500X I bought was Kevlar with a rudder. After researching all models on the net for about a year before buying, I am convinced that you will not find a similar new model anywhere for the price. If you have any questions contact me at my profile, and I will be happy to answer your questions. If you live in southeast PA. maybe we can set up a demo paddle. No, I do not work for QCC. I just want to help a company that has treated me very well, and their boats should set the standard for other companies to follow.
