I LOVE DARK WINTER ROM.
I have went from 6.0 straight to about 5 different 6.5 Non Josh Roms roms and they all ran slow had a lot of bugs. So I flashed to Dark Winter 6.1 and I love it. It is so fast and responsive, just the way the phone should be. In awhile I might upgrade to Josh's 6.5 roms but for now I am happy the way it is.
