Searches for Prince Phantom Pro 100P can lead to both the Pro-labelled frame and its successor, Phantom 100P. Tennis Warehouse reviewed the former in February 2018 and the second generation, with Pro removed, in January 2020.
The later review describes Twaron being added in the hoop and shaft. Its composition table changes from Textreme/Graphite to Textreme/Twaron/Graphite. That is the generation change documented by these two reviews.

Both tables list a 100-square-inch head, 27-inch length, 16×18 pattern and 20.5–19.5–16.5 mm beam. Their shared dimensions make the complete name and material marking useful identifiers.
For a used frame, obtain photographs of those markings and match them to the 2018 Pro review or 2020 successor review. Keep Phantom and the presence or absence of Pro on the order alongside 100P.
