If you mudglass it it should help it withstand a drop, It may still crack but it shouldn't crack into little pieces and would be easier to repair, I just noticed with rondo its brittle when its used alone, but when used with fiberglass cloth it just like using just fiberglass just a little stronger, but be careful or that helmet will start to get heavy
I noticed in your ref pictures the EOD has a light blue looking visor what are you planning to use for your visor, I built this helmet already its just in pep stage sitting in my closet I always liked the reach version better than the H3 version eod
