First time on my Reflex 6 - 8.6.
Wow, really nice sail! It is always tricky with a new sail, before you get the trim right and before you learn how to sail it... but the Reflex was just plug-and-play. I got a good trim almost directly and the sail felt really nice on the water. Lighter and easier to sail than I expected, with a comfortable stance. Not as much mast-foot pressure that I have been use to with large sails before, so I got the board flying nicely! 
Fantastic combo with the Isonic 110 and ZSF-42 fin!
Wind was about 5-8m/s
