Twinset wing for single, is it really that bad ? (Comparison to big jacket bcd)

You don't want to include sampling gear in your calculations. It should be light enough that it doesn't matter that much (tape measures and quadrats), or heavy enough that you use (or at least have access to) a lift bag (Hammers, chisles, pneumatic tools, etc). Plus you can always drop it if needed. I always tell my dive buddies and fellow researchers that if they seem me with my camera dangling from its tether, I need help. It means I have decided that whatever issue I'm dealing with is more important than a $15k camera.

Rescuing an overweighted diver requires ditching weights or rethinking your system (team, equipment, procedures, etc). Dual bladder wings are sometimes the best sub-optimal option.

The issue isn't that your approach is too cautious, it is that you being too cautious in your thinking is making you less safe.

Appropriately sized tanks/wing combo and a drysuit sound like what you need honestly. Doing working dives to 60m on air with not ideal equipment sounds like a terrible place to be. You should be having some safety talks with your team/PI/DSO. As a DSO, I would never approve that as a plan.

Yeah just to clarify, I am not doing work on air at 60m that sounds like a terrible idea. I was talking about different type of dive sorry for the lack of clarity. I also agree with you on the rescue part however modifing team/equipment is not always possible. Thank you for your advices.

@iointerrupt the 35lb ccr wings are a current alternative without resorting to finding an old apeks wtx3

From experience and training, use the right tool for the right job. I would not use a double-tank wing with a single-tank wing. I tried it once and will never do it again, even if the mfg. says it is OK. I use a 17kg/37lb wing for singles when diving locally in Libya (we use 18L steel tanks frequently when diving from boats) and a 13kg/30lb wing when traveling and will use <18L tanks. For double tanks, I use a double-tank Wing.

So you want to dive a steel single with a doubles wing, and a steel stage(s)? Sounds like you need doubles. Don't bother with goober gear like oversized poodle jackets, bungee wings, or doubles wings that claim to be O.K. for use with singles.

You could also just ditch all the extra gear you're carrying in case of emergency. I'd rather lose a camera rig than be pinned to the bottom a la Andre Smith. It sounds to me like you need to rethink your weighting strategy more than anything else.

The CMAS divers, primarily from France, frequently dive to 60 meters using air and single 15L steel tanks. They have been practicing this for a long time (since forever). This attitude and approach have influenced the diving culture here in Libya, where some individuals regularly engage in deep dives beyond recreational limits to even deeper than 60 meters using air (single tanks, seldom double tanks on air). Unfortunately, we also have one of the world's highest rates of diving-related deaths and injuries. The equipment used and the diving practices contribute significantly to this alarming rate. Factors such as a lack of proper training, inadequate medical care, and the unavailability of dedicated compression chambers for civilian non-commercial use intensify the issue.

A GUE instructor once put me in a oversized wing for doubles. Due to tacoing, it was very difficult to shift air to stay trim and not roll left or right. It is not fun spending your entire dive battling a roll.
