Each wreck has a tale to tell about its life and its demise.
If you are observant while diving in dark places listen to the account each has to tell, You cannot come away unaffected.

Using the suit as primary or exclusive buoyancy is in my view crazy and likely to lead to an accident, and regardless of what PADI may say I won't teach it that way.. IMO you should have enough air/argon in the suit to reduce squeeze and provide insulation, but any additional air should be in the BC. On the way up I always reduce the air in the suit first, so that the whole way up I still have air in the BC. Then in the event of an incipient ascent I can dump air from the BC, which is quick and predictable. Dumping air from the suit is usually slow and unpredictable, and if I need to lose air quickly is hazardous.
Sorry this may not be very clear - I'm suffering from a bad cold and not thinking clearly!

But I'm sure that after those first few dives you did feel in control.. Task-loading is not in itself a bad thing. Some types of diving have a vastly higher task load, but people manage OK.My drysuit course was taught by a PADI instructor, but she still taught me to use the suit inflator just to keep the squeeze off and my BC for bouyancy. I will say that I felt slightly task loaded inflating and deflating both for my first few dives
I often hear this, usually from warm water-only divers. Dry suits are usually used in cold water when you need lots of insulation at depth. Insulation = air which = excess buoyancy., so in cold water you cannot avoid having excess weight at depth which requires the addition of artificial buoyancy. You NEED air in your BC. If this guy was an instructor I would be wary of anything he said.Shortly after I took my drysuit course I did happen to be talking to a diver that turned out to be an instructor, I do not know what agency, he told me that if I needed air in my BC I was overweighted

"Correctly weighted" in cold water doesn't have the clear-cut definition that it has in warm water. The primary function of your drysuit is to provide insulation, and that depends on air being present. The colder it is the more air you will need, hence the more lead you'll need to allow you to descend. On a long deco dive in cold water I need enough air to provide adequate insulation at long deco stops (sometimes upwards of an hour) and that typically means I have to have several pounds more weight at the beginning of the dive.When you are correctly weighted and use a dry suit for buoyancy you will find ... there is no need for a BC. The BC is there in case of a major suit flood and considered the backup device
I don't see the point of having dual wings if one is disconnected and therefore unusable. When I dive with dual wings both are connected, and to opposite posts. I don't routinely use both but I ensure both are available to me.To offer a contrary argument to the use of a BC with a dry suit: If you use two buoyancy devices then you have two things to handle in an emergency. I have two wings on my technical rig. Only one is connected at any time for just that reason

Correctly weighted is correctly weighted. Water temp does not affect how much weight you carry. Salinity does. Wetsuit thickness does. Drysuit thermals do. However, a diver in 80F water who is properly weighted for the gear they have can dive in the same water with the same gear at 32F without a change in weight carried."Correctly weighted" in cold water doesn't have the clear-cut definition that it has in warm water.
