I was just sweeping thru old stuff and just wanted to drop my line and revive this interesting thread.
Much has been said for the both styles of play and I think they are compatible with each other, ie you can play and mix some type of tunes and then just go "warrior style" with others.
Almost any juggling sound makes some pauses and some Mc chat a bit so there's a pause between tunes but also an entertaining moment too...
I got used to play with 2 decks but this year played in a street fest in Lisbon with only one deck and the vibe was there the whole night until the cops told us to stop (@6:00am
With one TT I felt more concentrated in the moment, instead of being automatically preparing the next selection, I was more in tune with the massive... But I've seen great selectors do this with 2 decks.
I feel this one deck way a like a concert where the band puts on a song then a pause, singer chats and then some more vibes! But you can too have a band play long medleys or extended versions so there you go everything compatible!
Each sound should be doing what they do best either with one or two decks!!
