The Nantahala offers an excellent balance of power for a smooth stroke in a light weight and durable canoe paddle. Symmetrical blade shape designed for predictable forward paddling and maneuvering strokes.
Negatives would be questionable durability (but then it is light), rather thick shaft if you have small hands and it tends to flutter when pressed hard.
Great all rounder, but not for serious WW use.
I've paddled with a Mohawk paddle for years. I recently enjoyed a trip down the Nanatahala River with my new Werner Nantahala paddle but I couldn't tell much difference. It's a nice paddle, and it feels good but I would recommend trying one before spending the bucks.
I just got back from a trip using my new Werner Nantahala canoe paddle. It has a nice solid feel to it. It has a lot of power and appears to be very durable. The only negative is that it is a little thick for my medium-small hands. Other than that, I would definitely recommend it.
