I've had some time to ride all three now and had them out vs. an Aguera race board.
I agree that they are all faster downwind than pure race boards. However, I could not keep up on the upwind legs. As you would guess, the bigger the board and fins got, the closer I got to keeping up. Keep in mind I am a recreational rider and kite shop owner and I was riding against a world ranked racer.
I really love the texture on the boards that makes moving my feet around super easy and sticky. No wax needed.
Yesterday when I finished with lessons I took out the 54 in waist high surf with an 8m Ozone Reo and had a blast. Smacking those little lips was almost as easy as with a regular surf board. Bottom turns had more drive for sure and that made it harder to stay on the wave and hit it over and over. I've only ridden the 54 with one front strap and the swept fins.
Anyway, here are some pics of the 60 and 66 showing the deck shaping.
Of course, all the Sectors are jump on and go. The Aguera takes some practice.
