OK, I have to admit that I hate AT paddles and I've never used one. I cannot tell you guys how many broken ATs I've come across, including two this last weekend. I don't know the differences between the paddles, so maybe it's a problem with only one line, but my general impression is that they suck. I've personally seen at least 6 split in half and another handful with the broken blade/water in the shaft problem. You flat out couldn't pay me to take one on a multi-day trip or any run with serious commitment. If you're looking for your first bent shaft and expecting to lose it on a swim, then this may be the blade for you. If you only do roadside runs and like the half price of a Werner deal, then maybe this is the paddle for you. However, a friend this weekend snapped an AT2 on the shaft, just taking a paddle stroke without hitting anything. He had to C1 a class V rapid on the NF Payette - sketchy and it's still roadside. Then we had to beg all the paddlers in Banks to borrow a paddle so he could get out the next day and save the trip (thanks a ton Jeff from WA!).
My advice is to suck it up and buy a Werner. The blades will wear down over a few years, but it happens predictably and allows you to plan for buying a new paddle. Unlike the ATs, I've never seen one snap in half in the worst place possible. The Werner's are bomber and far away the best paddles on the market. Check the Powerhouse: Werner Powerhouse Paddle
. If you want to go run the shit, this is the paddle for you. If you stick with the AT, make sure to also buy the best break-down on the market - the Lendel Kinetic, you're gonna need it.
Diatribe over, but I'm really passionate about this topic. I apologize if I've offended any long time ATers out there.
