Curious to see what people are using for heavy undergarments and weight belt systems. What's best suited? IIRC I need about 20lbs with no kit on to stay down. Maybe slightly less, xm450 under and clx450 suit.
Depending on the necessary distribution, I would probably put 3kg per side in weight pockets and put 4kg on a weightbelt (that actually adds up to 22lbs but in ball park numbers this is what I would do).
The problem I find with more than 4kg on a weightbelt is that it's cumbersome on the one hand and if you make a lot of dives in a short time (like, say 20 dives in a week) then your back will never forgive you if you put much more on the weightbelt. For one dive, if you can somehow keep it all from slipping off then you could manage the whole 20 hanging on your back.
