I am getting more used to the 7m each time I use it. I took it out yesterday when I could have been on the 5m, and found that I was keeping the kite higher and more depowered.
It is interesting though how a one strut kite seems to be "softer" when a gust hits, i.e. it seems to absorb some of the gust. That can be handy, especially in the middle of a transition. Not so handy though if you need that gust to get going.
I am also loving the responsiveness of small kites, you can put them where they need to be much quicker than something bigger.
