Hi,
I’m curious about weighting when diving with a back plate and wing system. There’s a lot of information about weighing out there but I’m still not sure I’m properly weighting myself.

The gear on the tank:
Halcyon infinity Bp/w bcd. 30 pound wing and 1 pound aluminum plate. (No tank adapter)
Atomic brass 1st stage
Misc. gear not worth mentioning for weight

What I’m wearing:
Thin fourth element thermocline hood (2mm)
3mm full wetsuit
6.5mm fourth element boots
Mask (atomic frameless)
Apeks rk3 fins

Overall, I’m using about 9-10 lbs in the pool. The tank/bcd rig is neutrally buoyant in pool (with 500psi in the tank) So all of the weight seems to be needed for the wetsuit/fins/mask I’m wearing. I should also note I weigh about 150 lbs.

Does this seem right? After switching to a back plate wing system, I was told I should be able to get my weight down to about 6 or 7 pounds. Obviously it’s hard to know for sure without testing in the water. I’m wondering if 10 pounds sounds like too much weight in the pool. Wouldn’t this mean I need about 14 pounds in open water?

Any insight is greatly appreciated!
Just want to make sure I’m not overdoing my weight.
 
I didn't see much of a weight difference when I went to a BP. With an AL plate and no stabilizer my BPW set up was slightly lighter than my jacket BCD.
 
Seems heavy to me in the pool. I'm 5'11" and in a 3/2 wetsuit, I'm using 2 lbs in addition to a titanium bp and sta.

Did you weight the tank/bcd @ 500 psi with a fish or luggage scale?

I'm guessing you don't dive in the Sound. The wing seems a bit large for tropical water.
 
Aluminum goes almost neutral in the water so being told that you could shed a few pounds of weight off your added ballast is only partially true. The true part is that you can shed the weight that you had to add to offset the buoyancy of the jacket, not because you added any usable ballast going to an aluminum plate.
I’m assuming you were in a jacket? Correct me if I’m wrong.
The best test for perfect weighting is when you can hold a 15’ safety stop (5 m) at the end of your dive with a near empty tank and no air in your wing.
Where you place your added ballast to make up for your suit is up to you. Scubaboard seems split on whether it should be on a weightbelt or some other ditchable option, or secured onto the rig in a non ditchable fashion following the “balanced rig” philosophy.
