I kited over there in 2008, lots of people...
If you want semi uncrowded paddle surfing conditions, be prepared for paddling out in the dark before sunrise.
Wind wasn't the greatest when I was at Lakey's, a couple of days on the 11 and one day on the 7. Only two other kiters there when I went, a french (or euro of some sort?) who had been there for a while and another aussie dude.
I'm taking a month off middle of this year and exploring further east past Sumbawa...
