I explained that above. When you see it switching back and forth on its own, its because you are switching networks. Roaming networks usually only allow you to connect to 1x data and not EVDO, which is why you see the icon changing (otherwise you would have no idea what it is doing behind the scenes). Each time you connect to a network, it drains the battery.
However, it is not the 1X or EvDo switching that is killing it, but rather the fact that you are disconnecting and connecting to new networks in the background.
This is different from being connected to one tower, using the 1x side of it for a bit, and continuing your EV connection. They are both always active (although current CDMA networks only allow a phone to send/receive on one protocol at a time, putting the other on "hold". All the while the connection stays live and doesn't consume any additional battery power).
