At present, many players are playing these two kinds of rubber bands, such as the traditional bow-tie circular rubber band1636,2040; Some archers tend to play traditional high-tension bows and some rubber bands, such as1742,3060. This part of the archers feel that they have feelings for thick skin. Of course, it has something to do with everyone's situation. Some people can't pull such a heavy rubber band, so they choose a smaller one. But if you play with 8mm and 9mm steel balls, you can actually use 1636. No matter how thick the rubber band is, it is a waste of energy to practice strength. Of course, if you are playing such a big configuration as 10 mm,1mm, 12 mm, it can also use 2040, 1742. After all, everyone's preferences are different.
