Hi, first of all, english is not my languaje, sorry if I say something strange. I never make a slingshot, but inspired by the channel I'm working now on a 3d printed slingshot whit a vertical front pulley system, the idea is to use one single rubber to do all the ''circuit'', and make the point of draw directly to the fron, so I can gain distance. The major doubts that I have at the moment, is what wide I must cut the theraband gold, if I put x2 3cm I can get the same power than a 6cm? my goal is to make a slingshot as powerfull as possible, the strenght is not a problem. The other question, is that where is the limit? 6cm x3? x4? 8cm? is that a point where the contraction velocity of the bands just reach a top and the only gain there is just using more weigth in the projectile? Thank you.
