... get in contact with Rachel the physio when you get there. Not sure how to contact her from here but I'm sure there aren't too many Rachel's who are physio's working for defence in East Timor!
If the winds anything like Darwin, organise big gear too ie bigger twin tip and 14/17m kite or if you only got 12m then you might just have to wait for the good stuff to come.
I heard rumours there are wicked waves on the south part of the island but this report was from a non kiting dive boat operator who said he's seen Sumbawa and looked the same???? Dunno, but you might be able to find out for us????
Another idea just came to me, contact Geoff at Funsupply
funsupply.com.au/ , he used to fly there alot (air med pilot) and may have ideas too.
Good luck,
Robbie
