Reason I bought this up is, I was trying to talk myself into a single pin and can't do it. Here's my scenario from this past elk season. After an hour plus stalk on a bull to around 25yds, I released and clipped a limb, MISSED. Bull ran and I cow called him stopped about 40yds and then laced him. I was using a 4 pin fixed sight. I don't think I would have killed that bull with a single pin. I am however, considering a 3-4 pin adjustable. Just need to do more research.
