Hi Jules ,
We have been there in 2003 with Mogi group , the place is not too good for GT fishing , we started from BIMA and went all the way north until 60 nmiles from MAKASSAR and did not find good spot for GT popping , most of the reefs suffered illegal fishing method ( bombing ) .
As for Dragon , if you are referring Komodo giant lizard as such , they only exist in Komodo , Rinca and south west part of Flores islands .
In my opinion it's not worthwhile to go to Sabalana Atol , better concentrate in Komodo n the other islands in the east and west , specifically the south coasts .
Jon .
