i'm 63kg (140 pounds) and i mostly use my 10m or 12m here at long bay.
my heavier boyfriend has the 13m velocity and often a raceboard.
The wind generally picks up in the afternoon - it should even be possible for full moon kiting mid feb. If you want a downwinder/more spots come see us or Wayne at TCK
for sure, try treat yourself to kite session at little water cay (iguana island), we went and it was AWESOME. super flat, only us, brilliant time - but you need a boat or jetski lift!
