I was planning on buying Thera-Band Gold, but I'm on a budget, I was wondering about how much would someone need to last a few projects. I have poked around the forum a bit but could not find any topic pertaining to my need. I wanted to make The "Zombie Killer" Slingbow, and "Slingshot Crossbow Bullpup" For my first projects, then make my own. So I'd appreciate input. I want to be able to make my own slingshots other rubber based devices for fun. I know I could get cheaper Theraband colors, But, I would like to make powerful slings. If I have missed anything, Like information, or a topic that does have what i need, please tell me. Thanks you for your time everyone.
