Reply to Sync with 3 or 4 decks traktor pro

Hey guys... I would like to know your opinion on what is the best option to sync when you want to do it with 3 or 4 decks at the same time:

a) use the masterclok and the auto sync?
b) choosing master on the current deck A, B, C or D that I would like to be in that time and the others would be slaves?
c) other better alternative?

I would like to read your experienced opinions... thanks guys

cheers
