However, I found a simple solution some may not know about- a USB OTG and a flash drive! Turns out CWM supports backing up straight to a flash drive, as well as flashing zips from one. This saves on disk space, and is a bit safer (if your phone glitches you won't lose your backups). The ability to flash from a flash drive also is good for rescues, as you can provide a zip downloaded from a pc if you break something.
Hope this is as helpful to the community as it is to me.
