From my understanding, you (we... I'm in the same boat) can only flash stock based ROMs. Some, like Eclipse, are highly customized. I'm rooted and have Safestrap installed. Highly recommend you do the same.
Safestrap is an apk you install after rooting which installs a TWRP-based bootloader for Nandroid backup and flashing ROMs/files.
Here's some info I'd shared with another user:
Safestrap is an apk you install which loads a bootloader of sorts on your phone. When you boot up, you'd get an option to boot into a custom "recovery", even on locked phones. It's a modified version of TWRP. So, you install the app once rooted. I did it while on 4.2.2. Then you just need to find ROMs which devs have created specifically for Safestrap and flash that via recovery. Make sure to create a Nandroid backup (via recovery of course) before messing around with anything. There are two that I know of (both currently based on 4.4, but both devs plan to release 4.4.2 versions soon).

You can download the Safestrap 3.65 apk (which should work fine on rooted 4.4, but again.. I installed it while on 4.2.2) here: http://rootzwiki.com/topic/104161-re...65-2013-11-13/
