I have the 14SG and agree it is a great radio. One thing I am realizing, however, is how DJI's recent products take away the telemetry benefit of the radio (or at least that's my understanding). I'm looking at using an A2 and perhaps a lightbridge, but from what I can tell either (or both) would mean no telemetry on my radio (in the case of the A2, assuming one used it as the receiver), and that's a big loss. I really like the voltage information and alarm on the radio, and recently have been playing around with a current / mAh sensor that is very neat (link below). Giving that up won't be easy, but it seems the way that DJI is going it will be hard to avoid. Am I understanding things correctly? I don't have an A2 yet, and the lightbridge is not available, so I am reaching these conclusions based on specs and not experience.
