well some peeps stick to the 2 cuz its original but the point is what sets u like more? mixing with 2 u can show or listen with the crowd the tracks at their best having all those big & most important breaks,with 3 ive check most of mixes are just "middle+begining+begining" of the tracks but on the other hand u can show or once again hear some great mixing & tracks playing unique lets say one track with the other ones beat or bassline? but somtimes i find those mixes kinda confusing,
what type are u into more ?
