OK, I didn't know that Armory needs QT wallet to function.
AFAIK all wallets which download blockchain needs Bitcoin core unless they add Bitcoin core's functions to that wallet.
So Armory is not a 'light' wallet, then?
No but if you like to use Armory, you can use CounterWallet isntead of Armory online and Armory offline.
I currently use Multibit and was thinking of trying out another 'light' wallet.
Try Multibit-HD. It is in beta phase but it is good.
What are my options? Electrum?
Browser wallet: GreenAddress(recommemded).
Other wallets: Bither, Electrum and Multibit-HD.
