Hmm, Ive just have a 8m Sonic, which is my first kite, and was looking to get either the 11m or 14m as well.
I like to have 20kts when on the 8m, but can get going in 15kts. I'm looking for something good for the days between about 14-20kts. Im not too fussed about days much less than 15kts, go for a surf or kayak instead.
I weigh 70kgs, and have been wanting to add the 11m to my quiver, but judging by what carbine said, maybe am better of with the 14. I dont mind trading off a bit of bottom end for more optimal performance and comfort in 18-20kts though.
Decisions, decisions, or I could make it easy for myself and get all three
