I'm actually looking for DJtools sometimes... They aren't a main part of my sets, but sometimes it's just nice to be able to vary quickly by adding a loop here and there to two already banging tracks (in a 3 or more deck setup)

IMHO it should only be as an add-on to your set and not be used too much, altho it would be quite impressive to do a 2hr set with just DJ-tools, and still keep it interresting
