I'm new here, so forgive me if this has been answered or is a stupid statement. If the video assists still uses SDXC/SDHC it doesn't seem to overcome the limitations of the internal card. Whereas the Atomos Ninja 2 and preferably the Ninja blade while not perfect seem to at least solve a wealth of problems. Just getting an external monitor is adding more bulk and ungainliness to a rig, especially if you still need an external storage solution.
