GoNuke - I think the WNI price has dropped as all the shares they have issued to BRM holders are slowly cashed in... this will happen for quite some time based on the amount they have shelled out.
Kiwi - option 4/ hold until 90% and contest value with legal action if compulsory acquisition is attempted.
This could potentially take years, the longer they take the more chance of a payout for being a holder.
