How about bending the slingshot backwards?

First, the anti-bending slingshot is more in line with manual design than the straight bow. There are more reflex slingshots than straight bows on the market now.

Second, the reflex slingshots are mostly traditional bows, and the ball card reflects less.

Third, closing the waist without closing the waist has little effect on the bow, because we have to wrap the bow according to our own needs.

Finding a bow that suits you is the first step to play a slingshot well, but the key to accurate shooting lies in diligent practice.
