Todd Schmalhurstwrote a review of Werner Corryvrecken 2-Piece Paddle - Fiberglass Blades/Straight Shaft on August 15, 2011
This paddle has the same great features as found on other Werner Paddles, nice ferrule for easy and precise adjustment. This is a large, high angle paddle, so it's best suited for strong paddlers who want to go fast.
The Corryvrecken, and other paddles in the 'Premium' line from Werner, are a good value for the money. They aren't cheap, but it's a good bang-for-the-buck as compared to the full carbon fiber paddles.
