A lot of the top trance DJs who don't play progressive do quick cuts or much shorter transitions than those who play progressive. Seems like the higher energy music tends to work better with quick cuts. What could be cool is playing progressive for the first half and long transitions, then playing epic trance with quicker cuts. I mostly played epic trance for two years when I had TTs, and I would do quick cuts, and it's been more difficult to play progressive, that i've gotten more into vs. the higher energy stuff I was into before.

Haven't read the entire thread so I don't know if this has been said or not...

But I typicaly stay away from the quick cut transitions unless the track I am bringing in or the track going out has a huge build and then a crash at the beginning (incoming track) or end (outgoing track). Of course there are exceptions, but that is when I "normally" do them.

Square One - Vesuvius (Justin Martin's 'I Hope It Doesn't Blow Mix) is a perfect example and I actually used the quick cut transition with this track last weekend and it was really bad ass.
