Very nice! Did you get some shots of the Threshers? How was that part of the trip?
I had only 4 mornings where it was possible to go the Monad shoal for the threshers. However, each of those mornings was absolutely glorious. We had threshers every day and often several swimming in circles pretty close to us, being cleaned by cleaner wrasses. The photography part of the shark dives was less than optimal. First it was very early, so it was dark. Second, it was overcast, so the sun didn´t help much. Third, it is quite deep, and fourth, the visibility below 15 meters was not particularly good, with a brownish tone to the water as well. However, that said, the sharks were absolutely stunning, and there is no doubt that I will do those dives again as soon as I get back to the Philippines. It is such an amazing sight to see one of these big sharks slowly circling just at the drop off and being cleaned by a swarm of wrasses.
Here are a couple of pics just to give you an idea. Both of the sharks were at least three meters, and I would guess that the first was around fourish:
