$2 billion is certainly not inconceivable, but would be better if it were achieved through share price appreciation over share issue. That takes an aggressive approach. For this reason I prefer PTR to GDY, and greatly prefer GRKs chances of being a short to medium term 10 bagger (if management proves up to the task).

Anyway I'll have to leave it there. I said previously it is largely about sentiment at this stage. There aren't enough companies (and not even one producer) to give a meaningful comparison on fundamentals. PTR did propose a standard for reporting resources recently but no-one using it yet.
