Just recieved my new JP FSW and NP Firefly during the week and got out a couple of days ago in gusty 15-20kt conditions (gusts up to 25kts) off my "home" sailing area Salonika Beach (about 25mins south of Mackay).
The chop/swell here is messy at times and pretty bumpy but the board never felt out of control. It proved to be super manouverable on the face of swell/small waves and very fast when bearing off in gusts. Just the right amount of float for what I wanted giving me plenty of room of error in gybes. I weigh in at about 75kg and upgraded from a JP 261 freemove (89l) I brought new years ago. What was once a floater was now extremely marginal at best due to putting on about 12kg. It's nice to have the extra float in the stinger season up here.
The sail was very tuneable. To me changes in downhaul/outhaul were pretty apparent. Overall the sail was light, easy to handle and really suited the board in these conditions. For the ligher conditions, I am looking forwarded to trying out my 6.7 Hellcat - hopefully later this week.
