Really beautiful work, and a great story that makes it more powerful. I am so glad you posted this, because I share your curse. I've seen plenty of reef mantas over the years but never an oceanic, despite modest efforts to track them down (including an expensive wasted trip hunkering down under a typhoon in Yap). I need to pick better destinations, but luck and bottom time are all-important. Your shots are inspirational for the unfortunate!
As for improving the film, I have only one thought. I've always felt that remoras detract from the manta's beauty and are a visual distraction at best. They look like toads riding Ferraris. Could you remove them? :-)
Thanks for watching, and glad you liked it. I hope your curse ends soon. I would recommend Socorro to break it though. While we had bad weather, we eventually got a clear day to dive. The boiler is amazing.
I am not that good at editing, so I can't remove the remoras...sorry. ;-)
I can only speak to a couple of items on your list. As I haven't been to PG. Anilao is one of my favorite places. However September is still a risky time there for weather...normally October/November to May is the safe time.
As for club O. Been there twice. It is a great place, with great guides. Although, getting a hold of them can be tough. I recommend trying through their Facebook account. They have enough repeat business, they aren't too focused on gaining new clients. If that doesn't work out. There are other places that are good as well, like crystal blue.
As a side, I have done Atlantis resort in dumaguete and it was great. I am sure pg will be similar.
