You should equip each individual paladin differently so you can abuse...I mean take full advantage of the wound allocation rules. Like, 1 with a hvy weap, 1 justicar, 1 hammer, 1 halbred, 1 apothecary. That way the enemy has to do a total of 6 wounds (through term armor and FnP) for you to remove 1 paladin. To be more cost effective, as you will want apoths in every paladin squad but they are rather expensive, form up to 10 man units. You can still equip every single paladin differently even in a 10 man squad.
