Just download the full rooted stock ROM in android development and flash it without wipe from recovery.
It's actually fewer steps anyway.
OTA = revert system changes, boot recovery, flash, re-flash recovery, re-root
Rooted stock = boot recovery, flash
No brainer really. Flashing an OTA if rooted is a fool's errand

Had to reflash SU and amend my build.prop to get the LCD density back to 480
After the first reboot it came up and offered me the OTA ! Hopefully it's not going to keep doing that.
