Exactly what I was thinking.

Hold on to your shirts kids, here comes some physics:
Force = mass * acceleration

(whew!)
The heavier rings will have a greater force of impact if allowed to fall the same distance as the lighter rings, and if they hit the same spot. Calculating the actual force of impact takes the rest of the kinematic equations (as well as some experimentation to figure out distance of deceleration & duration of impact. In any event, more force = more spring extension or more cantilevered polycarbonate sheet deformation.

As for the rules -- I don't believe springs are allowed. However, surgical tubing and deformation of polycarbonate are allowed.
