Harness adjustment question

[benha]

Yup. I put my weight on a belt, not on the plate. And yup - rodeo bug diving. I've been rolled up into the rocks often enough that I now wear a whitewater kayaking helmet.

I'm not setting up for tech at all. I switched to plate / harness situation because it's easier to get in and out of when I switch to the long hose to crawl into cracks to get lobsters. If I dove dry I'd just use a plastic backpack, but I dive wet so I need a wing and they tend to mate well with plates not the plastic backpacks.

Regardless, my concern is _not_ about being neutral. My concern is in getting as close to evenly distributed density as possible. Buoyancy affects whether it goes up or down. Distribution of density affects how it orients itself regardless of whether it's rising, falling or stable. With a 119 on my back and a little evidence of one or two more beers than I needed on my gut there's a huge natural bias for the system (me) to roll over. I was just thinking about ways to try to reduce that natural bias by doing more than just throwing lead at it, since it's tough to position enough lead as far from the centerline as the system as would be needed to compensate for the tank weight.

Anyway, this all falls in the "hairbrained scheme" bucket.

That tank shows a buoyancy of -11 full or -2 empty or there abouts. What if you take the tank off and mount 6-8 lbs of lead on the backplate / tank straps to somewhat simulate it in the water?

Are you using an SS back plate? If you're using steel tanks you could switch to an Alumn. BP and then shift most of your ballast forward with a weight belt or weight pockets.
