5 VSDs would cover a lot of real estate with their arcs too. Might consider staggering them in a 3 in front, 2 behind W formation. If someone does get behind you, they eat the front arc of at least one of the second row vics. I'd be really interested to try this out actually. feels imperial too.
Other option might be a line of 4 with a single rear guard. I might consider a demolisher as the rear guard so it can respond to anything that makes it past the line.
