Listening to a pure house mix I made a few days ago. But to keep some kind of energy, I mixed using all four of the decks on offer with Traktor.
I don't think it sounds too bad. 122BPM - 128BPM is not that fast so it feels very "warm-up".
I usually mix 2 dance genres. so in that sense, pure house was house only. no electro. no techno. no progressive. no trance. just good old house beats.
EDIT: Give it a wee listen. For me that's what i think of when i think about house music. Club house is more commercial. Tech house has more of a baseline to it. and electro is like dubstep for girls.
I tend to play what ever i feel on that given day. I don't like sticking to one genre. I'm always mixing techno with electro. trance with progressive. and house with tech house. club house with electro. the list goes on...
