There's a goal here in that if a load can be worked out adequately to achieve deer kills at 200+/- then I would prefer to do that without a lot of holdover.

a single fixed peep takes away the versatility of chunking a big piece of lead downrange.

Most, if not all of my local hunting stands provide close range FOV, but have at least one tree line that is between 160 yards to 220 yards either along a bean field or the edge of a cutover, especially my back porch which provides a 220 yard shot to the treeline across the field. So a flipping rear will let me engage targets in both "worlds" so to speak.
