Hi all,
So I've got a little trip planned . A long weekend down to Cyprus to spend a few dives diving the Zenobia (Zenobia Shipwreck Diving Larnaca Cyprus). I did 6 dives on it last year on a back-mounted single steel 15l (HP120) + little 3l backup (20cuft or so), and it's a cracking dive. The top is around 15m (50ft) and the sea bed is around 42m (140ft).
Definitely recommend it if you're ever in the area.
This year I'm going back and I've arranged to have two Ali80's waiting for me so I can spend a bit longer, have some redundancy and go side-mount. Should be great.
Thing is, I've only ever dived side-mount in the UK, where I'm either in a Dry-suit or thick neoprene wet-suit, and using my 12l (HP100) or 7l (Guess that'd be about an HP55). Obviously my weighting and trim is going to be very different. It's going to be more like what I read people are doing on here.
So.... In my thin wet-suit I have about neutral buoyancy with no lead on. My understanding is that Ali80's are about neutral when full (maybe a bit nose heavy with regs & valve), and go floaty when empty. I don't really have any experience with them. How much lead do people have on to cope with them going floaty?
Doing the calcs I reckon there's about 6 lbs of gas in each cylinder. So I'd be wearing about 12lbs? Does that sound about right? or is that over the top?
Would you put the weight on the tanks or on me?
Anything else I need to think about?

BTW: I hadn't actually looked at the video on that site. It just came up in Google with lots of good pics on it.
Not quite sure why the camera is filming that guys butt more than the wreck.
