Most of the folks on this forum are whitewater paddlers. The design of whitewater kayak paddles differs from flat water paddles. I have used an AMT expedition by aquabound paddle for flat water cruzin' in the past and found it to be comfortable and light weight. Recommended! You can probably pick one up for about $130 - $150. Confluence Kayaks in Denver may be a place to start.
I have 2 superlight carbon/kevlar paddles for sale. They are costa rican designed and created. I can make them any length or offset you like. I live in BV, so if you are in the area and would like to try one give me a call.
