A friend of mine is a physical therapist. I asked him if they used any Theraband and he said all that he had was used strips except a brand new roll of Blue. Being as I typically shoot small ammo .177 bb's and 1/4" I told him I asked him if I could get some. He brought me a 3 foot strip. I looked at it briefly and stuck it with my other elastics. I got the small roll out today to cut some bands and noticed that it says "Non-Latex". I didn't know there was such a thing. Well to make a long story short (sort of anyway) I went ahead and cut my bands and tied them onto one of my natty's and took it out for a spin. I don't have a chrony but my soda can test (lining up several soda cans one behind the other and shooting them from a distance of 10 feet yielded comparable results to my Latex TBB. So we will have to see how well it holds up. Have any of you folks out there in Slingshot Land had any experience with this band material? What are your opinions?
