Having just had my first surf on a sup (see "a kook again" post) I noticed an extraordinary amount of flex in the adjustable paddle i am using, which has been fine for the flat water paddling I have been doing. It really did not feel as if it was going to last very long. I am 115kg and 5'10 so am putting a fair amount of pressure on the paddle when trying to catch a wave. Pretty sure I am going to have to upgrade but don't really know what to look for. Have tried manufacturers pages but just confusing the hell out of me. Any help would be greatly appreciated.
