Fantastic! Thanks for sharing these.
If you have time, would you like to write a piece on diving in Statia? Not many people do it and, as we can see from your pics, it's an interesting place. Even above water, it's a fascinating island with history all around.
Definitely an upgrade from the Inon Z240. Can't say though from the Z330.
If you are snooting, the circular flash tubes of the Retra with the centralised pilot light made a world of difference over the Z240.
Are you pleased with the Marelux pro snoot? Looks very cool and I really like the idea of the adjustable aperture. Does that work ok? I've heard anecdotally that the iris mechanism can be problematic.
