I dont even see it as a BPM thing, I think that can get a bit too elitist also,
I like 140 but I am with you all the way on moving away from endless Distance copies
I think its more about the vibes & sounds, the best D&B always had light & dark, it had CONTRAST (some of Groove's epic sets at Blue Note as an example)
The music just needs contrast, and dubstep is now where DnB went (PEAK all night, full revs in 5th gear)
