I am still a little confused. I have all of my BTC in paper wallets. so if the fork does happen, I can choose what network to import the keys into when I decide to spend them? also what if I want to switch networks? do I just make a new paper wallet and then import it into the other network? I also cant see how both wallets can exist in both networks, since they allow us to have double the coins. will their just be a blockchain.info that shows the balance for your paper wallet on bitcoin QT and a blockchainXT that shows the balance for the paper wallet on the XT network?

Thanks
