Groove carbon $405 Aus +frieght 450 grams .Manta Ali light equivalent 700 grams $216 Aus + freight . Or the Mac kiting Ali plate for only $200 Aus delivered. All still look super chunky and have to create drag paddling back out .Good way to pick up 100m in length of mast not so good for learning but a plus when you charge bigger waves. The original Manta was 1kg , I bought one it and felt like a brick in your hand. Here are some shots of the adaptors available now. The Groove looks nice but is it worth the extra money to save 250 grams and the Camet guys are dreaming.
