I have trouble juggling hip-hop, let alone attempting dnb. I find it's a whole lot easier to drum with hip-hop and dnb than it is to juggle.
On another note, I've gotten to the point where I can drum a hip-hop beat and make it sound like a dnb break, and a dnb break into a hip-hop beat. The main problem I have is keeping rythym while drumming, as it's difficult (for me) to drum at a steady pace for longer than a minute or two...
