I tried various combos. I think the loop that I set up, 42" semi-cirles with 36" straight connectors, was too small to let the spring action function "well". It did stretch in the curve but stayed stretched a bit coming out until the car or cars behind it exited the curve as well. By then it was almost ready to enter the other semi-circle. Just too small I think.
But it did prove that it works.
