For an American Wheat I suggest WLP320 American Hefe yeast or the WYeast equivalent. It will give you the cloudy "wheat beer" look and still ferment cleaner unlike a european hefe yeast, though in my experience will still provide some clove flavor (no banana).
WLP051 or WLP001 both are not really suited if you want a true American Wheat beer. Unless you were trying for something like an American Kristalweizen, which is a wheat beer that is filtered and clear, if thats the case I suggest WLP051, it'll provide slightly more fruity flavors.
