What style are you looking for.
For waves, West Java (Turtles) or Sumbawa (Lakey's).
I did Lakey's and got a fair bit of wind when I was over there (late July). Only one other kiter, but I was told there is usually more.
Had a couple of kites in Lombok, around Kuta area. Waves no where near as good, but the people were amazed by it, like they have never seen it before. Wind wasn't as strong either.
Try a search here on Sumbawa.

Or just sheep it up with all the others at Sanur...
