2060 rubber band or 4070 rubber band, which pulls more?

4070 rubber band. The advantage of wearing a rubber band inside the 4070 is to improve the initial penetration. Inner wear is a form of cocktail. The principle is that the center of gravity of the rubber band moves to the side close to the slingshot because the front is thick and the back is thin. After the rubber band is full, the moving distance of the center of gravity decreases, and the time for the center of gravity to rebound to its original position in the same time is reduced on the premise that the resilience of the rubber band remains unchanged. Therefore, the tension of the rubber band of 4070 is greater than that of 2060.
