I thought one rom would wipe out what was previously installed..?
You got it wrong you need 160mb system partition for this rom. when you install the rom you install both cm-10-20130129-EXPERIMENTAL-blade-DAEMOND.zip and gapps-jb-20121017-KonstaKANG.zip
The first file is the rom without any google apps such as the play store, gmail ect to install these you install the second file
to change your partitions you need to tpt your blade
