Interesting paddle. Seems most modern paddles are very flat. I prefer thick canoe paddles with an airfoil shape because they have lift. I assume that the Greenland paddles also have lift due to their thickness. I am a canoer with 50 years experience and many paddles, this is my first kayak. I want to try it wit my favorite canoe paddle too. I've learned to rotate the canoe paddle instead of making "j" strokes, simply rotate at the end of the stroke.
