I'm just like you. Except I've had major experience here in the ROM game.
First off - BackSide is extremely outdated and no longer a recommendation. OV-KitKat here is currently the only KK ROM for OV.
Regarding other ROMs, the most stable GB is MiRaGe, the most stable ICS is PAC-ROM, and the most stable JB is SlimRom - SlimBean.
I'll be glad to guide you step by step in installing those ROMs and figuring out your ultimate best setup. Besides, I need the experience to add to my Android hacking portfolio.
PM me and we'll setup somewhere to talk.
I had trouble being certain of what I Googled as SlimRom - SlimBean was for my phone. I also have some concerns about ICS for VM670 (Optimus V) as I haven't heard anything about it ever having been stable in any way.
What I'd like to know is what is believed to be the most stable among each of those. I figure that the lower the version of android, the more stable as whatever is closest to Froyo would be closer to the original build; is this reasoning accurate? Are the Froyo ROMS the best for something like stablity?
