Good for you to have discovered kitesurfing..
! Its an addictive sport!
I am in the Philippines now and if I were you i wouldn't go to Asia from mid april and may. It is totally right that the two spots is friendly to beginners, but there is NO wind from marts-june in Asia.
If I were you, I would check out Venezuela. Its cheap and it has a lot of different spots. AND IT HAS WIND IN APRIL AND MAY
