It truely is personal preference. I like a single pin mover because it is less confusing and less cluttered. With todays bows, the pin gap is so small all the pins just blur together, and besides, I am notorious for using the wrong pin.

With a single pin, none of that to worry about, just setting the proper yardage. I leave my pin set at 25 yards while hunting. It shoots 1" high at 20 yards and 1" low at 30 yards, so I don't have to mess w/ it unless the deer is beyond 30 yards. That's why I choose a single pin and will NEVER use a multiple pin sight again.
