5 STYLES OF YOYOING
1A is basic style of yoyoing that most of yoyoers start with. In this style you do string tricks with 1 yoyo attached to your hand. String is attached to the yoyo. Apart from 1A there are so called "alternative styles of yoyoing" (2A - 5A).
2A aka "Looping", two yoyos, one in each hand, looping tricks. Looping yoyos have imperial shape and are responsive.
3A, two yoyos, one in each hand, string tricks.
4A is also called "Offstring", in this style player uses yoyo that is not attached to the string so it can fly in the air.
5A aka "Freehand" uses one yoyo that is not attached to player's finger. Instead there is counterweight attached to the string.
