I tried a 15 deg in the pool and loved it, I really like the offset and the paddle was very light, stiff and responsive; had good bite and power as well. Plus for half the price of the other carbon blades on the market, its hard to pass up.
I have a 30 deg Werner and a 0 deg Seven2, I don't really like the 0 but that could be because I don't like the flex in the Seven2. The 15 was an easy transition from the 30.
I have Facebooked and emailed Ferd, now I just wait. Someone really needs to build this guy a website...
