Tails.......removable
Could take off.
.
I recall seeing a far clunkier version of this idea advertised in US surf mags years ago. I like the thinking but question whether the advantages of different tail shapes are worth the installation process. Doesn't look simple.
Well i thought it looks like a great idea,its only a matter of screwing the tail on like a fin in a fin box but we'll see when Noel Salas does his other tests on them . They look well made out of carbon fiber ....anyway if you like tinkering around with your board for different feels ,a lot like changing fins for same reason,then its probably worth looking into.
