Re: How legal are tension springs?

I don't think that tension springs are necessary. Surgical tubing is essentially the same thing, but with a feel-good squishiness that will make your life better. Plus, it's free in the KOP!

We did a quickie catapult test yesterday using two loops of surgical tubing stretched 2 feet. It launched the ball with about 4 feet of loft. By doubling up the tubing, we should be able to get the necessary height on our next try.
