Survivor, I see no point in wasting precious resources on an enemy that far out numbers me. Hunting them only brings me closer to them.... not part of my plan. They are dead, they may rot slower due to the virus but they will rot, I can wait, time is on my side.
Without a doubt, a survivor. First because... I would be a terrible hunter, that would most likely hurt herself than killing anything really dangerous. Second, because guns are pretty hard to find in my country. If I get one, I wouldn't want to waste bullets if not in danger. But I would put traps around my town, pointed out with red paint or signs, so other survivors wouldn't fell in (it's not like zombies would ever get it, anyway).
I like your idea's, but coming back to your traps and finding a couple rotters trapped still makes you a hunter. Not directly but they prey eventually came to you and you do end up successfully ensnaring them :)
I find this mental picture funny, imagine stalking a zombie then when close enough yell,"Yo, dead head, catch!" As you throw a bear trap at it xD
