Coming from 2 HTC devices in the past, I certainly wouldn't. It takes forever to get a good AOSP rom on them. CM for the Incredible did work well at the end, but the Thunderbolt has yet to recieve a truly 100% functional AOSP rom. CM 7.1.1 is ok, but its unofficial so you wait months for the changes to move into your build, Liquid Smooth is ... not "smooth" at all for me. Its sad, I dislike MIUI but its what I'm using at the moment because its the most fluid. Tired of all the screen lag on the other AOSP roms.
