I hop around ROMs, but only remember one bug from Viper... For some reason after a few weeks it stopped using high res pictures for facebook contacts and used low res versions of the same pictures instead. That's always bugged me... Like nails on a blackboard. It's why I can't use Senseless ROMs. Viper's battery live was pretty awesome for Sense.
Oh, just remembered, there were some graphical glitches in a few apps.. like Pool.. the screen where you have to agree to the user policy was always a white screen so I couldn't agree to it. A minor thing since I could restore data from a previous ROM.
I'll probably be back on it soon... Especially if there's an update.
