Paul Wallace who is also know as Gsimian, is a yo-yoer and inventor. He created and runs G-String which is a high end yo-yo string manufacture. G-String is a very unique kind of yo-yo string that uses polyester, which is very soft compared to normal 100% polyester. G-String is also known for its fun and exciting color combinations.
Paul was also a founding creator of Caribou Lodge Yo-Yo Works with his friend Chris Mikulin (whom is now in charge). Paul is no longer active in CLYW.
