well the way i see it is that a set like that can go down well but at the start of the night mainly. For me when i am on the dancefloor i like it really tuff not necesseraly 145 fast but maybe 138-140 if its really kicking off. Thats in respect to a techno night but if you played a set like that at a club with a broader musical range ie bugged out then i think something like that may go down well. Its just down to where you are. Your right though about when your playing harder more people do get on the dancefloor and i don't think this will ever change. Can't see more people at a techno night on the dancefloor to a slow set than to a quite hard one. Just the way things are i think.
