In which scenario are head guys typically used?

Head guys are typically used on steep hills to counteract downhill strain. This application is crucial because when poles are installed on sloped terrains, the potential for the poles to lean or fall over due to gravitational pull increases significantly. The head guy provides additional support and tension, helping to stabilize the poles and prevent them from tipping as they bear the weight of the lines they carry.

In contrast, using head guys on flat terrain, in urban areas, or where poles are closely spaced does not address the specific need for stabilization against downhill strain. On flat terrains, poles are less likely to experience significant leaning, while in urban areas or closely spaced configurations, other forms of support and tension management may be more appropriate due to the different environmental challenges posed.
