If you are looking for a low wind kite consider a Flysurfer Speed.
Flysurfers have exceptional low wind preformance and jump well even in the light stuff. I use the Speed 17 and at 225 lbs I can ride staying upwind in 8 mph and jump in 10mph.
Last Saturday I had a blast with it in low winds and large swell. I kept away from the shore break, rocky and real bad wind lulls, but got some great jumps about 20 yards out from the break. Winds were 8 to short gusts of maybe 14mph. Swell was big building to 10 to 12 foot but with high intervals and comming in in predictable sets. Sending the kite from the top of these even with 10 to 12 mph wind made for some huge jumps and the hangtime on the Speed 17 is fenomenal.. it's like a small paraglider.. felt like I could have tea and buscuits up there
A few other people were out, but were riding either surfboards, big directionals or were feather weights.

in this video just look at how much faster the Speed than the other kites out... wind was 10 to 12 mph
The Speed being a foil is different to fly compared to a LEI, personally I prefer the Speed. If your experience you can get the knak of the Speed in a couple of hours. Relaunchability in winds of 10 or more is great. below that it is tricky. The problem is that you can ride in 7 mph and it's hard to relaunch anything in less than that. The Speed is an ultra high projected aspect ratio kite and the 17 has the power of a 25meter LEI
