Samsung Galaxy S2 : Alternative ROMs

I took some time to look around for alternative ROMs, here is a quick list of my findings:

Villain ROM : rooted ROM and deodexed, some optimized apps. For the install, follow the guide
Lite’ning ROM : new skin, tweaks from 2.3.4, optimized apps, circular battery, rooted ROM and a few other good things (this is what i am currently running)
Cyanogen Mod : Not avalaible yet but very active development, we should see something within the next 2 months.
