Shuyun Tang, founder of Original Throw, and his friends have worked with factories to make the “perfect” yo-yo strings which could handle all styles. They sent sample strings to over 100 players all over China and after 9 prototypes they believe they've created the perfect strings!
OT Normal string (24 Threads) is great for slacks and whips and cuts through the air with ease. It has a soft feel that is gently on the hands and is great for those extra long practice sessions.
