Parting Line Height-- where the top and bottoms of the disc essentially meet. A higher PLH or higher edge of the rim from the bottom of the disc generally means more over-stable flying. The opposite is true where if the edge of the rim sits equal with the bottom of the disc it will fly less stable. Setting a disc down flat side by side is the easiest way to tell. the edges of the rims should meet if the same mold or one will be higher/lower given its respective stability.
