I'll keep looking for ya..
As for the best rom... I have no idea.. I will say this though. If you have the international model of the s2..Do Not Flash Any Roms from the epic 4g touch forum.. you will end up with a soft brick or worse a new shiny coaster.. If you get our bootloader stuck on that device.. chances are Odin nor anything else will recognize it and you will be stuck hoping a jtag can save ya...
There is a forum for that specific device..
EDIT.... I'm a retard... I see what you're asking now.. lol. I'm not sure as I'm a boost Customer but I would imagine that the tw based roms would be the better choice..
E4GT : Project X Bare Bones
GT-P7510 : JB 4.3 CM 10.2/SGT7
Thanks Dev's for these Awesome Roms...
