For Border provinces i try to go pd20, maybe as high as 30-40 if its very important or i have no army near. As a general rule of thumb i try to place one recruited archer/crossbow in a province (atleast) for each point of pd. I add battle mages if i have cheap mages with great spells (any nation with e2+ is good(as are many others), summon earthpower, spam bladewind) because, while you often want them with your main armies the sort of damage they can do is amazing (nether bolts, bladewind, falling frost/fires, a few of the clouds ect)
