I was considering usnig Electrum to create a cold storage setup, however I have been convinced that using anything but a full client is insanity. Look at the recent events as posted by theymos on the sticky:
https://bitcointalk.org/index.php?topic=5090097.0Just stick to full blockchains. Get a full client that you can trust like Core, run it in an online computer with no coins, then run another Core client in the airgapped computer. Move raw transactions into the online computer and broadcast them.
I don't see why bother with any other software. "As a newbie" is not really an excuse. Start with the real thing. Developing bad habits its not good in Bitcoin.
