I find NMM only looks good from certain angles. Admire the guys that paint it, but it's made for 2D photos imho, not 3D gameplay.etc. That said, actually working on this for game models as i really want to learn the technique, and these videos are fantastic for it!

Still haven't seen enough of them to decide if I'm buying them but this video is pushing in that direction.

Are you planing to make sets for non typical metalics? Like f.e. red, blue, purple nmm?
