Mule Deer: I agree about 2 points for irons but a ghost ring receiver sight only requires concentrating on the front sight. The eye automatically centers the front sight in the hole. Aagaard's test had the scope very slightly faster than the peep sight. Scope does allow for avoiding brush.
Sorry, but unless the stock is set up to align your eye closely behind the ghost ring, it does not work that way. Instead you still may have to align your head) slightly to get your eye behind the ghost ring AND front sight, while even a 2.5x scope (which is what Finn used on his .375 H&H) is faster--because the scope's ocular lens is a LOT wider than the ghost ring. It provides an instant look the entire FOV even if slightly misaligned, with the reticle plainly visible.
Which exactly why Finn's test indicated the scope was faster than a ghost ring--and even though the advantage was slight, any time saved can be critical in that sort of situation.
