No use for the flysurfer in January, you'll get some use though, my ozone zephyr 17 has been a great investment, generally its 10mtr and smaller from october till march,
I'm 100kgs and used my 10m Psycho4 pretty consistently when I wasn't using the 15m Speed 3. Last summer was pretty flat for wind and the 15 got a huge work out. So I'm a little biased and would tellya to bring your Flying doona just out of solidarity!
