One of the points that I disagree with Tobin on is that a person needs to know the following independently of each other in order to make good buoyancy decisions
Their individual buoyancy, either positive or negative. Mine is 2lbs negative, most are a pound or so positive.
Suit buoyancy
rig buoyancy
only then can you accurately calculate how much ballast you need to take. The suit buoyancy is especially important because for many people wearing a wetsuit can adversely effect how they breathe which is bad, and they can also trap air pockets, also bad during your weight checks.
Ah, not sure what we disagree on. I too want to know the suit buoyancy and max negative of the rig.
Personal buoyancy will impact total weighting, but does not always impact required wing lift. Buoyancy Compensators are used to compensate for things that change WRT depth, and personal buoyancy doesn't change WRT to depth as long as the diver is breathing compressed gas.

I currently am Diving with a Halcyon Single Wing with integrated weights. Do I have to much on me
I have a Single Tank adaptor Weight 6 Lbs
I have a Steel BackPlate 6 Lbs
tank band weight pouches 2 on bottom band 2 on top 16 Lbs Between the Two
Dropable Weight Pouches 10 Lbs Between the two
I have a total of 38 Lbs of Lead carried all on the rig
I am afraid that I have to much weight. I dont know what to do
Thanks for the help
I suspect you are overweighted, but there are other concerns as well.
You have:
6 lbs of plate and harness
6 lbs of STA
16 lbs in pouches on the cambands
10 lbs in pouches on waist band
2 lbs of regulator
??lbs of full cylinder(typical full al 80 is -2 lbs, typical full steel is -9~-12 lbs)
Without *any tank* you have a rig that is ~-40 lbs. AFAIK largest Halcyon wing offers 40 lbs of lift.
With even a full al 80 you are at -42 lbs
With say a full HP 100 you are at -50 lbs.
I'd suggest you test your suit to determine just how buoyant it is. That will give you a huge clue about total weighting.
I'd also suggest you move some of your ballast off your rig and onto your person on either a belt or weight harness.
