Check out the new JP Carbon paddle, these are high quality, well priced paddles.
not a "top end paddle".....to quote the presenter
.....still unsuccessfully trying to snap the Ke Nalu X-tuff shaft
JP (Neil Pryde Group) is probably the biggest supplier of shafts to the world, they make shafts for a lot of the bigger companies in the market today.
I think you will find that they will pass any test.
AS mentioned this is a video on the standard, middle range paddle. JP also make a full top end paddle ( which costs $150 more) is 100 grams lighter (450 grams total) and paddles like a dream. 
Cheers
