I use the ICSSGS 4.2 for a longer time in dayli use and it was very stable and fast and I liked it a lot. As the ICSSGS team now works a longer time on the next step I decide to keep my eyes open for another nice ROM and find the Tirmaisu 1.9
I use it now since some days and its a pretty nice ROM with provide so many options for customizing while beeing very stable and no lagging. Also it is simmilar fast then the ICSSGS, maybe slightly faster from how it feel and also form Benchmark (3223 in AnTuTu).
Also the AROMA installer which is implemented is realy great and in the next version of the Tiramisu ROM the Installer will offer a wide range of languages to make it even more comfortable.
