John, Julie and I use this gear:
3 x Nikon D7000 (1 spare), 2 x Subal ND7000 housings, 2 x Inon Z240s, 4 x YS110 (2 spare) all strobes with fiber optic connection, Stix float arms, 2 x Nikon 105mm, 2 x Tokina 10-17mm, 1 x 1.4 TC, 1 x macromate, 3 x hartenberger focus lights (1 spare), ultralight clamps.
We had 1 minor malfunction. The AE-L/AF-L button on the back (re-assigned as autofocus button with autofocus removed from release button), did not work properly on 1 of the subal housings, driving Julie insane. It looked like there's a spring that wasn't working right. We took it apart ourselves and re-seated everything, which helped a bit, but not very long. Then Garry the cruise director did it again, and ever since things have been working ok.
I know 1 person had a lot of trouble with his housing, but i'll leave that up to him to discuss if he feels like it
There were 3 floods, one pretty serious, but amazingly no gear was damaged. Leak detectors rock.
