I'm really liking this, I've picked Quickman as my first choice for GRMRB and seem to be the only one who has him as their first choice, so hopefully I won't tread on any of your ideas when I do my version.
As I said I am really enjoying this, my main complaint though is the first lead (the one that's used at first from :34 to 1:02) it just seems a bit underwhelming and a bit lifeless given the energy of the backing. I think just using a bit of vibrato on it could work wonders.
That really is my only complaint with this though, I love the hard hitting sound of the drums and the overall soundscape, and from 3:00 onwards, genius!
