So what is the advice for Armory users post Aug 1st hard fork?
I'll just move btc after the split to a new address and then export the keys of the then empty btc addresses.
Import into bitcoinABC and send with their wallet.
As long you've the private keys you can handle it how ever you want.
Just make sure you don't use the addresses where you exported the keys and imported to online wallets.
If you want to be sure you could create a tmp new armory wallet. Move BTC before the split to it.
After the split move them back to your normal wallet and then export the key(s) from the tmp wallet and import them into an ABC supporting wallet.
If you don't plan to spend them you could also just name your tmp wallet "ABC" and keep the coins there.
Even if you can't spend them (yet) with armory they would be secure in Armory.
