Hi. Yes foxup, I´m aware about the no difference between Hyb and C but I have the same curiosity than you about the difference between these and the Pro. I don´t know if the added flex that the kork provides, make it sweeter in the waves or not and also if it´s like sameh says that it´s so hard to find the difference. I´ve seen some images and videos about the incredible flexibility of the kiteboards with kork but don´t know if it would be the same in the SUP´s. Any way, I´m not hurry. Now it´s winter here, the water is about 13ºC (will be worst in january) and these days the sea is a little angered and seems to want to go out of the beach so I´ll wait to get more information before to decide. Thanks
