Just to throw in another opinion, I paddle with a 45 degree offset paddle and think it is quite ideal. I have paddled with a breakdown werner that had holes drilled for both a 45 degree as well and a 0 degree offset and experimented with the 0 feather and didn't like it at all. I started out paddling with and 80 degree offset paddle when that was the standard, so what I'm used to is somewhat skewed here. With a 45 degree offset I don't find that I'm using an obvious control hand or making any pain or discomfort causing adjustments between strokes. Certainly not to say that there's a right or wrong answer here, just what you're used to.
Also I would ad the point that I heard some years ago that higher offset paddles not only aid in paddling in a head wind but also in big water type situations when punching big holes or waves where the paddler is taking the low line and punching through or plugging under the hole and has one paddle blade deep and engaged in the water it allows the offset blade to catches less of the slack/recirculating water or foam pile. A small point and I'm not even so sure that it's a legit one.
