The old light wind argument, kite vs board who will win this time.
Lucky for you your a bit of a light weight and you would probably get away with a bigger board like a slingshot glide with the 9m kite should get going in just over 10kts, or there is the nobile skim board which is a lot easyer to ride than it looks, or grab a big old surfboard and get out there.
The problem with bigger kites in light conditions is they are heavier, turn slower and a lot of the time you would still need the bigger board. But a small kite can still turn fast in light conditions and generate more aparent wind and still get you going in the light condition on the bigger board.
it really depends on what your aim is, are you just looking at going out for a cruise or do you want a bit of power for tricks, jumps etc.
If its just crusing then grab a 12m kite and ride your current board but you may find you dont make your 10knts that you want to get out in. Or grab the big board and use your 9m and see how light you can ride.
If you still want to do tricks, jumps (little ones) you will deffinatly need the bigger kite and the bigger board. Last years 14m bandit dos was a great light wind kite, as was the 15m rev. Or you could lash out and go for the ultimate light wind kites like the flysurfer. All these kites will get you out in 10kts but will handle like a old rusty tractor turn slowly etc but will also pull like a tractor. Then board wise you would need a larger tt board than you would normally ride like the light wind NHP that nobile make.
Really i think light wind kiting is more about how deep your pockets are as the bigger kites cost a lot more, more expense on bigger boards, and for what a lot of the time you still only get a quick ride or get blown off the watter.
Best money i have ever spent on light wind gear is definatly the nobile skim.
Looking at your wind chart i would be sugest that you dont set your goals so low there is so much difference between 10kts and 13 kts and at 13 kts you would definatly get away with just the bigger kite.
I hope your confused as that is what light wind kitting is about, there is a lot of options and what suits one rider wont suit another. There is only one real solution that would 100% solve your problem,
MOVE SOMEWHERE MORE WINDY
