Don't mean to steal your thunder or anything, but been there, done that
Made this vid about two and a half weeks ago, and then proceeded to use this build to grind up to merc elite
I love your vids btw and I think you'll do a way more fantastic job than me. If you want any footage let me know, I spent a fair amount of time looking for the best 0.06G planet with a high intensity CZ to do this.
Edit: Just to add, I added improved sprint shortly after because I found that using L-6s significantly encumber you and slow you down if you need to move about the map (there aren't many small maps where all the drop points are within range of a single reload/recharge point, and you will eventually find yourself having to reposition from time to time and running out of stamina). This significantly improved the kill count performance
