Wow, that is pretty impressive and also pretty cool.
I agree with your statement about damaged safety glasses. They may seem OK but it is best to keep them clean and in good condition.
We always clean our classes before regionals but we also carry cleaner for them during the competition. You can find cleaner nearly everywhere.
BTW, is it true this year that shaded glasses aren't allowed in the pits? I had heard this but I couldn't find it in the manual.
They should be banned, they are not very good.
