At 90kg with the 7m I find I can go with a door board in 12-13knots(a few whitecaps on the outside, others on 12-15m kites) just staying upwind and cruising...not much fun, but I can stay upwind easily...surfboard would be more fun probably.
At 16knots on a smaller twin the kite comes alive! It really is different when the kite is on. More so than any other kite I've tried, you either sink, or your kite is set. Strange really, but it works.
I find the same thing under 10knots, the kite just isn't happy. Not sure why, but it doesn't bother me as I don't fly it ever in those winds. Kite is heavily built so that might have something to do with it? dunno.
That being said the kite is AWESOME in good wind. I fly it from about 16-32knots with a smaller twin and it is FAST turning AND flying. It flies upwind, jumps high, has descent depower to where I've never once touched the depower strap, but do need to edge in gusts a bit. I took it to the gorge as my only kite and it was VERY gusty...kite did great. I'd say for a guy my size the 9m would have been better for lighter winds, but the 7m is just so sweet and fast that I'd have missed it. Right now, it is my only kite, and I use it from 12-32knots with two boards...the large board is HUGE, so it's not much fun until I'm on the smaller twin at about 15-16knots, and above 20knots I FLY!
Fun kite, well built, fast, not expensive, and just does what I want...might want a light wind kite someday though...but I dread slow big kites, especially after using the 7m.
However, while I believe the Ovandos are very powerful for their size I think they are a bit overbuilt to be uber light wind kites...just my opinion though.
I love the 7m though and won't be giving it up anytime soon...great kite!
