I find the main prob I have with dancing to DnB is that it's got an underlying fast breakbeat, with a slow overlay. Have been to a few DnB clubs in London, and they kinda lurch all over the place. Feet firmly planted on the ground, and these crazy knee lunges going on. Looks way cool though.
I find breakbeat the easiest to dance to (Melbourne shuffle-wise) 'cos it's constantly changing, yet you can predict when a sample, scratching, etc. will be thrown in and you can time your spin, whatever to match it.
When it's just 4 on the floor, it can get a bit tedious.
