Honestly Alex, I'd swap out that polycarbonate for HDPE if you can - that'd probably save a nice bit of weight, I'd imagine!

And haha it is Sam, I'll give you that! Your huge, uber-power bar caused a 2cm wide crack in 2mm hdpe

Haha indeed I do Dave! I meant to come over and say hi at some point, but it's hard putting a face to names. Rancid seemed to hold up really well, may end up borrowing a few ideas with the aluminium angle haha!
