I also use a CHESS trading broker. At present I'm just trying to get the shares out of IG and their custodial arrangement into my CHESS account so I can at least feel like I still own the shares, but IG don't seem to be coming to the party in allowing me to transfer them off-market.
I'm fairly bullish in regard to AVZ being able to win their various legal battles and get things moving, so I guess we'll see what happens. A similar result to you 20x over a decade would be awesome actually, but I won't hold my breath.
