I use paper wallets to store my bitcoins... i have around 7 -10 wallets now, I use multiple just to make sure the others are safe when one wallet is hacked. I don't have much coins though, but that's the safest way i could think of right now to keep them safe.
I need to do the same, your method is much more secure. I am thinking about ding it, but I am lazy. Currently I have little in Coinbase, little in Electrum, and some in btcjam. I stop loan out bitcoin in btcjam any more. I don't have much myself.
