I agree that the supersaw business in after the intro was kinda meh. And it wasn't really THAT off. I just used triplets there, which usually works out in dnb and it sounded fine for me at the time.
That's actually a problem for me - things sound better when you're working on them for hours. And when you return to it after a while, it sounds like crap.
As for the plugins, I used harmor for the bass, trancedrive for the lowpassed triplet saw thing and soundfonts + samples for the other stuff.
