Had my 1st speed session sins a long time !! was good fun in the challenging conditions in tarifa with small waves chop and gusty and shifty winds . I used the 6.4 vapor 015 pre production and it was feeling sweet , easy stable and good acceleration . was also the 1st time on the hotrod 27 wich i did not get friends with , it was fine upwind but as soon as I went on the fin downwind and put some pressure it started spinning out so maybe to small for the board or the fin just doesn't suit my board , I tried the 29 yesterday and that fin felt very powerfull for its size and even big for 7.1 but guessing good for competition speed .
