Duncan has made a new set of counterweights for any 5A plays you imagine, This set includes three counterweights in the bag and You can loop out the string into the counterweight and play your yoyo with your counterweight for 5A tricks
Freehand (5A)[edit]
In freehand tricks, the yo-yo's string is not tied to the player's hand, instead ending in a counterweight. The counterweight is then thrown from hand to hand and used as an additional element in the trick.
Developed in 1999 by Steve Brown, as of 2008 freehand is considered to be the fastest-growing style of yo-yo play. Steve Brown was awarded a patent on his freehand yo-yo system, which was assigned to Flambeau Products (Duncan's parent company). Duncan patented the counterweight, and no one was able to design a unique weight.[17] However, since March 28th, 2020, the patent has expired.
In yo-yo competitions, counterweight yo-yos are emphasized in the 5A division
