You should never be putting all your weights in one system above a certain point. Diving dry or with a heavy wetsuit is one of those times. Reason is if for example you would have to ditch some weight or worse that weight somehow came out would you still be able to control your ascent. If you are using 32 lbs in a drysuit and one of the pockets comes loose or you need to drop some weight say to deal with a bc that fails how much do you need to lose to actually get going up? The answer if properly weighted to begin with is not very much. Maybe as little as 2-4 lbs. Now you go and dump one pocket. 16lbs is now gone. A little air in the suit and you are heading up like a rocket. I have not dove a weight integrated bc for a couple years now outside of the pool. And even there I use a belt.
The last time I dove a weight integrated bc dry with an al 8o the weight was distributed in the following manner. total of 28 lbs needed. 5 in each trim pocket, 4 in each weight pocket, and 8 on a belt. My plan was that IF I did need to drop any underwater it was going to be one of the pockets. 4lbs was more than enough to get going up and still maintain a good bit of control. My buddy also appreciated that I did not have all that weight in the bc and so did I when it came time to lift it.
The last time I dove dry with singles was in my DSS BPW with steel plate, 8lb bolt on weight plates, a steel 85, and 10 on the belt. The belt I use has individual pockets that I can drop weight out of in 2lb increments. The fron two are readily accessible and will allow me to drop that 4 lbs which is the max I would need to. This was by the way on a boat in Monterey.
Whatever route you go the first thing you need to do is a proper weight check and work on getting to what is referred to as a balanced rig. This should be where you have enough weight to get down and safely hold a stop yet still be able to swim the rig up in the case of a wing or suit failure. It is unlikely that both will fail but in the event they do you do not want ot be so overweighted that you can't still swim it up and if need be ditch the bc. I have not had a chance to do this with my new drysuit. Ear problem has me out of the water for a week or so. Soon as it's cleared I'll be doing this.
