I got my Nano S yesterday, thats why im sweeping one of the wallets now 
Why are you sweeping those coins? The paper wallets are still your most secure method to store those coins. After the last firmware upgrade and the Man-in-the-middle attacks on the Ledger, I am hesitant to move coins from cold storage to my hardware wallets. The idea behind paper wallets is to store coins for long-term and if you not going to use those coins, why then move it to a hardware wallet?
Remember : Those paper wallets might still have forked coins. Do not throw them away.
I'm spending some of it, that's why i'm transferring to the ledger.
The hack has had me a little worried, but for someone without a complete understanding of how bitcoin works, it still seems like the safest way, for when you want to spend coins.
Im keeping the other two paper wallets.
Any BTC airdrop between january 12, and march 29?
Ok, just do not do all of them at once. Do a test run with one wallet and monitor that wallet. Also see if the forked coins were swept from that wallet, before you sweep the rest or the wallets with the bigger amounts.
I have several Ledger wallets with the firmware upgraded and I have never lost any coins, so you should be fine. I have to say, Ledger reacted very quick and it was not really a hack. It was more a exploit that could have led to people losing coins, if they did not patch the firmware.
