I'll be waiting for the higher current board. Although I have not killed any more CC-Lite boards, I use a 1.1A PolyFuse in series with the motors on any CC-Lite install. A PolyFuse rated at 3A will not kick off until a significantly higher current in time to save anything, so I'd revisit your specifications.
I wasn't trying to test the robustness of the system when I had the flameout, it just happened.
