Hi, I use 2015 FX's. They are great kites although I find the bigger sizes are a bit of a let down. In 25+ knots on a 6, 8 or 10 I highly recommend these kites, super fast and predictable loops with decent pull

. I find on the 12 and 14 from 12-20 knots the low end isn't great, the super light bar pressure really doesn't help in these winds. A lot of other people who I know have also tried the kite have said the same thing,"the 14m has similar power to a lot of 12m in the same wind"
