YoYoFactory's Loop 900 yo-yo. As a result of Japan's Team Shaqler winning first place in the World Yo-Yo Contest "Artistic Performance" division, YoYoFactory released the Shaqler edition.
The Loop 900 came with a size K bearing, traditional starburst response, and a nylon spacer. This yo-yo was designed specifically for looping, also known as 2A play. Just as a short ski length can help your ability to turn quicker in snow, using a shorter string with this model, can improve your looping speed. If you watch professional looping players, they all use very short strings. But to further refine and improve your looping ability, the Loop 900 comes with a key that you insert into the tiny hole of the side of the yo-yo. By slightly turning the key clockwise or counter-clockwise, you can adjust the gap width between the halves and thereby fine tune its responsiveness.
