i spent heaps of time, effort and dollars on this idea earlier this year. i got very close with the Carbonerro team and almost ordered a custom eldoble paddle but decided to make a prototype myself first.
i used it on both my mana 10' and fly 12'6" and found it to be great but tiresome for cruising in a straight line but suprisingly slower than swinging a single blade only
i really wanted it to work but it's been chopped up and put out with the rubbish
i can detail more in a pm if you want
