I love the AT3 Zen for river running and creeking. I lost my first one and I just replaced it at Golden Riversports. I'm glad I did because I heard they stopped making them.
The reason I like it is because the blades are thick and look bomber and it is inexpensive compared to similar paddles. It is in the $250 range. I had 2 creeking seasons on my first AT3 Zen and it looked great. I can't pay more than $250 for a paddle because no matter what kind it is it is going to get lost or die young.
I had a bent shaft werner that I trashed in 1/2 season. It was abuse on my part, but I'm not buying a paddle with thin blades again. I completely crushed that thing in one bad day on Clear Creek of the Ark. My very first paddle was a straight shaft werner and when I was done with it the blades were about the size of my hands. Those thin blades just vanish if you creek with them.
The only problem I have with the AT3 is that they are black and blue and I was lucky to find mine underwater in a log jam once. They are invisible underwater. I'm putting yellow electrical tape on my new blades.
