Originally Chinese Dankung slingshots are mostly equipped with tube band sets. Even now the flat bands become popular world widely, there are still many shooters sticking to tube band set because of its better longevity.
All these band sets have GREAT ELASTICITY from high quality natural latex tube to make slingshot band set. This brings a strong retraction with high velocity.
Tubes (loops) at two sides are tied with minimized discrepancy. And of course there should be some difference because of handcraft work.
HIGH CONCENTRICITY between the inner and outer circles brings stable performance
