I've been using the Woody paddle for about a month now and it is super durable. The fact that it isn't a hollow shaft makes it have great flex and it won't crease. I creased a waterstick last year, and it fell apart at the lip of a drop further down stream (although I have to admit the Waterstick feel would be my second choice). The Woody paddles come in four different weights, I'm using the Kreek'r weight. It is slightly heavier than an AT2 but the air core blades make it paddle light because it keeps the blade floaty near the surface of the water.
The maker Wayne and I both agree that no paddle is unbreakable, but I truly believe that I don't want to be holding on to my paddle if I break it because it's going to be one hell of a hit. It survived getting momentarily wedged on Adrenaline falls in Lime creek last weekend.
Oh yeah, and the retail price is the same or comparable to the Werner's and AT's. Around $360. I know CKS is carrying them.
In terms of the original post, if you have had broken wrists in the past then you are basically going to be forced to use Bent Shafts to be comfortable, and most of the above mentioned paddles will do the job.
my rambling 2 cents.
