Has anyone tried rodimus? I'm still deciding which ROM to start out with.
I use Rodimus (and have for a while, since the 1.2.3 release was fairly new). I recently switched to the Bumblebee kernel (but kept the Rodimus rom) and have been very happy with my phone. It runs fast, the battery life is great (for a smart phone that is), I really like the Rodimus blue/black theme, etc.
Really, I would just pick one and go with it. Honestly, depending on how much customization you end up doing, after installing the rom, the one you start with won't change tons (unless you are debating between froyo or gingerbread roms, in which case there are some noticeable difference between the two).
Rodimus isn't really developed/supported anymore, but I stick with it because I use Go Launcher Ex (which none of the others do anyway), Link2SD which only some of the kernels support (including Bumblebee, which is why I switched to it), I removed a lot of the stuff Rodimus left in that other roms take out, and I really like the blue/black theme and don't want to bother trying to recreate it with UOT or something for another ROM.
Really, the differences in the roms is just the choice of starting points. Some start out almost as stripped down as you can get (Harmonia for example), while others try to throw lots of things in (reborn, the sense looking one, etc.) I really think it is more a matter of choice between froyo and gingerbread. Then just pick one and start customizing to your own liking from there on out.
