I have owned both. The AT2 is by far and away my choice. To me the AT is about 100 times better. Now for the durability issue. I had a DD for about 4 months, and it began to show sever wear almost immediately. I did what I could and treated it like a baby but it continued. One day a friend offered to take it off my hands, and I took him up on the offer. I immediately went out and purchased another AT2. I have beat the hell out of a few AT's and I have never ever broken one. I have never babied them either.
The AT2 got a reputation a few years ago as a paddle that wasn't very durable. From what I have heard the problems people have had have been with the old AT4's and the AT2 flexi. If you get an AT2 E(fiberglass), standard (Yellow shaft), or the Super Light i think you will be very impressed by the feel, the action, and the durability. If you have the same experiences I have had you will never even consider paddling anything else.
