Thank you both - this is exciting news. I will look into both Gangga (have checked before I know) and Murex (dove with one of the co-owners on a LOB last year) for Bangka.
Do either of you have trip reports or photo galleries for Bangka? Komodo reefs are the ones I know the best -- can you give me a comparison of Bangka or Alor to Komodo (or anywhere else you think might be helpful)? Are there a lot of current dives there? My buddy is not a huge drift diving fan, and it is not easy for photography often.
Luko I imagine you have dive op suggestions for Alor too

Is it mostly muck or mostly reef?
Halmahera - yes I have heard of that region and was curious. But one site I found says Oct-Dec & Mar-Apr are the best times to dive there. Recommendations for dive op? Weda maybe?
