I am also seeking some advice. I just bought a new 5'10" PN. I am an experienced surfer at 93 kg's & 6ft. I have an FST with the FCS fin set up. I have ridden it twice now as a quad with PC5 front fins and GXQ trailers. Today it was 2-3ft & fattish. One thing I found was that on a couple of occasions, when doing backhand re-entries the board would slide. Has anyone else experienced this. On a positive note the board has heaps of speed and is quite maneuverable. Not sure if the sliding is just because my fins are too small. I am going to ride again I the morning and plan to try as a thruster.
Any thoughts would be appreciated
