Bit of size at the local beach today, managed a few fun ones but was pretty iffy, had to really pick the right one then get out before it detonated on the shallow sand bank!
Been playing around with the single fin location, when was smaller earlier in the week I moved it towards the back to get the pivot game happening (work in progress) and today moved it up just past centre. Fin is this one:

Perfect spot for it as it found the sweet spot when swinging into some of todays waves, it drew the perfect line and got me out of jail - no pumping or anything required just take it off the leash and go along for the ride - was stoked!
