I haven't touched a slingshot since I was like 10. I had the version with only the single surgical tube set. The velocity with three sets must be awesome, but sort of wonder about how to keep the bands balanced. But yeah, with some practice, one can get pretty darn accurate. When you're like 8,9,10, you have LOTS of time to practice. Haha. Not sure about lethal with a chicken, but there were lots of "targets" in the neighborhood that weren't safe out to about 30 yards or so.
