Just bought new Novas after my old pair cracked at the hinge. Was always an issue with the original design, can’t complain about overall durability and these updated ones are supposed to be better. I like them but thing is they’re specialized for cruising: very efficient at medium speed, great for fighting current or covering area, but not versatile. Those big floppy paddles on the end of long hinges are not great for walking, travelling, precise motion, or inside confined spaces. I love them but if you only own one pair get the more normal Quatros instead.
