i've just got mine
I paddled AT2 SL for year, the paddle is sick, but i can't stand its 30deg offset, and had been trying to find used or good deal on AT2 SL or DD 0 deg for 6 months, until I tired of it, and finally cough up money to pay for the full price of DD 0 deg small shaft. Well, DD is also sick. I feel the blades of AT are smoother. However, my new DD is noticeably lighter, plus the blades are tad bit smaller than AT's, so it needs a bit less effort for each stoke but might be less power !?. The cool thing is the bent shaft of DD is less bent than AT, I can twist the blade backwards and paddle backwards less awkward than AT, the blades is more symmetry than AT's which is useful when the paddle is upside down after throwing in the air or helicopter. 0 Deg is awesome, I had my first underwater double pump in the first attempt in the pool, I was blown away. My weak side backdeck roll is not anymore weak with 0, it's so awesome !!!. I approve DD 0 deg, especially playboating.
