Just make sure you declare that at the weigh in.

BTW: 8mm thick steel lid on Satanix, minor nick marks from LH and Tinyhurtz . I did find out either 720 or Drumroll managed to bend a corner when it hit the top horns..

6mm HDPE on Hell's Angel took the blows, plenty of deep cuts but none went through. HDPE is lighter and cheaper than polycarb, something to bear in mind.
