Why not use giants at TH8 for a tank on outside wiz towers? The hp may be the same as hogs but having a wiz tower firing at the giant and not a whole group of hogs puts all the damage on 1 expendable troop rather than a pack of hogs all eating up the same amount of damage. That will let you heal deeper into a base with outside wiz towers or a base where the wiz tower radius reaches the wall the giant is sitting on.
