If you divide your weight into thirds, and wear 1/3 on your weight belt, and the other 2/3 in the two weight pouches of the Zeagle, that should work pretty good for you.
Then if you need to ditch your weight, you can ditch progressively rather than all at once.
Plus with 1/3 on your belt, you will find it easier to mount your B/C as well, or else it would be really heavy with over 20 lbs on it, together with the tank.
Back in the day, when I also had a Zeagle B/C, this is what I did.
Since then, Deep Sea Supply has come out with weight plates that attached to backplates, so when the Zeagle finally wore out after 5 years, I adapted the backplate for single-tank diving as well by attaching 2 DSS weight plates to it instead.
I think you will enjoy the Zeagle. It is like a BPW except made of fabric.
