Bragger1982....its not as difficult as you think to us custom ROMs. I found the easy was is to us TWRP backup. My advise is to make nandroid backups frequently until you are comfortable with your ROM. Once you have a good backup, you can bounce around from ROM to ROM and not worry about any issues.
I currently have backups on my SD card for Liquidsmooth, Liquid Touchwiz, CyanogenMod and Stock TW. It is also very important to back up your apps using TitaniumBackup.
