Aqua Lung Rogue Tank Issue

[jeffsky29]

I own a large Aqua Lung BCD, for a few years. I always dive a steel 100 tank, with 8lbs of weight. I really like this BC, except I deal with one issue on every dive. The tank always feels like it is on my right or left side, rather than the middle of my back. I am constantly jerking the BC, to get the tank centered. I would prefer to resolve this issue rather than start shopping for a new BC.

Is anyone else experiencing this issue?
Were you able to resolve the tank movement?
Is it because there is a lot of unsupported tank below the aqua lung tank strap?

Thanks,

Jeff

How tight is your waistband? Steel tanks will feel wobbly compared to aluminum tanks because they are less buoyant.

Waistband is snug.

The problem is that the Rogue, I think, like the Zuma and a number of other BCs designed for easy packing and travel, has a soft plate. A very negative steel 100/80 will tend to flop side to side as a result. The solution is to use an aluminum 80/64 but that may not work for you. The other solution is a BC with a hard plate incorporated in the design or a BP/wing.
