I found great improvement in changing to one arm hangs.
I did one arm hangs and really struggled with shoulder/body(?) stability so moved to weighted two handed hangs. I'm currently at +35kg (~60% bodyweight) which feels a little uncomfortable, but it is just a couple of heavy plates hanging off the front of my harness. I'd imagine with a better distributed weighting I could get up to close to double bodyweigth in reasonable comfort, which I'd personally prefer to one arm hanging.
Like this? quite common.
