ive been using a super 10 kite by flexifoil and really gotten the hang of it. sooo addictive. but i think it has its limits and i have reached them, im now looking for something with more power and enjoyment, something which i'll be able to use for landboarding in the near future. Could you recommend me a kite, giving the sizes as well ?

now i weigh 115 pounds which is quite light but ive just turned 15, and the wind speeds i have to deal with are between 5=at very max 21mph

Thanks everyone

I would suggest the Scout from HQ. Great kite that will get you set up perfectly for the Landboard. For size, look at something in the 3 meter size. That should work good for you and your current winds.
