I'm a powerlifter and we use bands in our training. But not like the thera bands, they come as a continuous loop and come in many different sizes and strengths. Here is a link that I found on ebay, its for a set of monster mini bands, the second strongest.

Has anyone ever tried them on a catapult?

I haven't, but they look like heavy pallet bands, which are tough but slow. That doesn't mean these will be slow, but normally we talk about sub millimetre thicknesses being reasonable and half mm being fast. Try them out. Pull them and release them; do they make a snapping noise like a whipcrack or do you hear a dull 'thuck'?
