i have always argued for multi approach that when we go to demos and wish to present our case it should be with more than one leaflet. There should be various texts and designs emphasising the different aspects from different angles.I do take issue though that we have only 3 seconds to make an impact.In my experience most people glance at the leaflet, (the 3 seconds) but then stuff the leaflet along with all the others they have been given into their pockets or bag and on the return trip home or in the pub afterwards, they go through the leaflets more attentively. Only the worse sort of leaflet is discarded immediately it is handed out. Its why i suggest we also a 4 page newspaper type leaflet as well as the smaller, to present a meatier analysis.
