Beautifully windy and I'm stuck here because it's too strong for me.
I took my 10m out to Melville Sunday and had a good time bodydragging, but decided I'd better go home when I started getting gusts that lifted me halfway out the water with kite nice n still at 12 o'clock. Got home and discovered the gusts were only about 22kts.
Soooo... what would you experts recommend? a) get a smaller kite or b) stick with it going out in 15kt winds until I improve?
I don't lose control of the kite in gusts, just don't like shooting off downwind without a choice in the matter...

good question, but im way no expert.
I figure that the guys who boost big are just the guys who have learned to edge hard and keep the kite low to the water till theyre ready to unleash.
gusts are just bad full stop.
dont buy a smaller kite.
get out more in consistent cross onshore wind.
you learn more when your comfortable and having fun.
dont stay out if your getting beaten up by weather/wind/rain,come back tomorrow.
dont be someone who used to kitesurf! theyre worse than people who "would like to try that one day"
i ramble i think.
next...........

its good to hear that you know when its time to come in.
keep it safe.

no one likes kiting in gusty winds - this winter take a look at how many kites you see out there even when its windy - not many xcept those who are dying for kite.

its a bit of catch 22 really - you put a big kite up in winter to catch the lighter winds, but you'll get blown hard in those frontal gusts, or you put a small kite up and only have fun in the gusts...

anyway to answer your qs,
keep your kite and get more experience in consistent winds first
