Alor has some great jigging spots for Dogtooth, notably around the Pulau Kambing sea mount.
Be warned though that the bust off rate is enormous - these are huge and very feisty Doggies that live their whole life in raging currents. On my trip to Alor last November we had bust off after bust off from unstoppable fish. Given the wicked currents, jig weight minimum 500 grams and often 700-800 required. Jigging at night is especially exciting there!
As Andy says, Komodo and the other parts of Flores are better known for popping GTs. There are notable jigging spots to the south around Sumba and the skipper of the Hatteras mentioned knows these well.
On gear, I fished PE8 and PE10 for GTs mostly with chuggers 120 to 180 grams. There are 50 kg+ fish there. so some might recommend PE12. Personally I absolutely hate fishing with line that heavy anywhere.
If you are there in the preferred October to January period, the light casting for tuna is a lot of fun and there are also much bigger YFTs to be had.
