rolling gage can be done with two spreads, 3 is better or 3 spreads and a lab your laughin. Its all about timing, once you get your head round it its easy. All lay it on to begin with, one drop back and start laying down while others carry on, 2nd man in team can drop bk if needed and just have one putting on,follow same principal with troweling stages, you all just muck in and drop bk on walls to do what ever stage needs to be done. GOOD COMMUNICATION helps, let each other know what wall need trowels or laying down ect
