I've had just over 200 sessions, and used 238 kite"sizes" (meaning, around 35 times I've rigged and used more than one kite).
150 of these, are 7 and 9m2
And the rest smaller and bigger kites...
Can not complain really, eventhough we dont kite that much when winther as it can be -18 degree (0 F) so NO surf at all then, but not for that long usually, so sessions also in the winthertime here, usually waves as the wind is tough
