There are some repeaters that use yagis - mostly in terrain such as you
describe. I don't know about the stacking, but stacked or not, the yagi
will 'aim' your signal where you need it. After all, there is little use
'pounding' your signal omni into the sides of the mountain. You may as
well get the extra gain down the valley. Maybe by stacked, they meant
one pointing down the valley and another pointing up? There are few
pitfalls. The only one I can think of is decreased range to the sides
(again, into the mountains) and back (which is why you may want another
pointed in that direction).
