Snowlord wins the Light with 382
Dark medal goes to Ioncorpse with 556
Congratulations to both for the amazing solutions presented.
There may be some doubts about Snowlord solution was classified as light.
Criteria I used for this: Welding is permitted and accepted as "light" as long as it does not, expontaneusly, explodes the intersecting material. This is the case in Snowlord solution. The cloth only tears up under the impact of the falling metal sheet.
I was a little surprised to see that all submissions gave the same remedy to the headache by dropping the AR directly in to right side of the nose. No one went to the top thru the brains.
My solution, not competing obviously, choses a different route: the left side of the nose. I am including it in the package just for the delight of the "light solution" fans.
