three decks are also nice not just to have 3 tracks going at the same time, but easy to use to cue and mix faster. while deck one is playing, get deck two cued and ready, then cue the deck three. drop deck two in, get one and two going strong, and then if you don't want to clutter that particular mix, drop out one and drop in three way faster.

i find that a little bit of having three at the same time and also using three in a row to cue and mix quickly is sometimes a lot better than trying to have all three in the mix all the time.

did that make sense? ;)
