The Duncan Rapid Ball Counterweight features a groove around the middle so there is no need to take the string off your yoyo – just take the slipknot off your finger and put into the groove and you’re ready to play 5A! The slipknot holds the counterweight very securely, so there is no need to worry about the counterweight flying off the string. The slipknot can also be passed through the hole in the middle just like a regular counterweight if you would prefer.
The Rapid Ball has a rounded shape with golf ball like dimples that is very comfortable to hold and cuts through the air with ease. The Rapid Ball is tremendously convenient and is sure to be a player favorite.
