Gave the ng+ a try as well. Bunch of cool new routes. I think loading the thruster cutscene from another file should be allowed since it's basically just the same as drek skip, which is allowed in normal ng+ (you just let the drek boss timer run out and load another file and you're set up). The rilgar in particular is just a really funny looking strat. Also packless ship to boss in umbris is pretty sick, but you need to turn mid hover so kinda tricky.
