One stand or two?

Say you place a 4 stand in a location and it's doing great. You want to add more heads. Do you swap it out for one big stand or just add another 4 stand? One advantage I see to using multiple 4 stands is that they are easier to handle if you are working alone.

I would probably do a larger rack because then you can add 2" and flat vend.  For most locations, (4) 1" selections is plenty.  If you don't want to do a bigger rack, another option (if they are cool with gumballs) is setting a spiral or other interactive gumball machine next to the 4-way.
