Last level of the original levels or the expansion? If you're talking the original, I like to have soldiers at the end of each path with totem towers in front of them to take out the invisible guys, Mech units with all upgrades in front of them and then the "raise army of skeleton warrior" towers in the front. Crossbow towers in between.
