Decided I'd take a chance, and ordered a Vixen ergo paddle sized at 230. I gave custom shaft width sizing for the ergo bend dimensions, as some ergo grips are wider than I prefer for touring use.
The paddle has carbon blades with a wood shaft that is oval, and it is a well made work of art. The spoon shaped blades have the right combination of bite, grab, energy used, and power returned for me.
The performance is great! For a few hours of paddling, it compares well to the all carbon paddles I have used. My rating is based on how I felt at the end of a few hours of paddling, and I felt a yearning for the next time. The ergo grip is a winner!
Big pluses for me are the aesthetics of the wood/carbon combo, and the ergo grip comfort. Very smooth throughout.
