With a draw length of 27 inches I think it may also be the angle of the peep sight itself. Check out Speciality Archery Hooded Ball peeps. It comes in three different angles. They have a chart to match your draw length and brace height so that the peep hole is perpendicular to your eye at full draw. I would recommend the 1/4aperturefor low light and the 3/16aperturefor day hunting.
