I use a laminated Aleut paddle made to Rob's plans. The only picture I have is alongside my double but if you copy the picture, you save it and then enlarge it for a better view of the paddle. I use the Aleut in preference to my graphite euro, even though it weighs a little more. It's a very easy paddle on the shoulders and I can paddle all day with it. It's also quite powerful when needed as well as quiet going into the water. I confess I've never used a Greenland paddle so I can't make any comparison.
