I was going to say how cool is that! My power kite is made from dyneema! I understand now about it needing to be 'hard' to withstand knife strokes (and therefore brittle by default).

I've nearly finished building with the chopping board and it's becoming pretty obvious it needs a lot of strengthening once you load it up with the wheel etc. I will take your advice and re-cut everything from a better material once I have some more money in the summer. I'm already having to sort steel plate reinforcements for the top where it will mount together.

I was also hoping that it would be mostly protected by the outer shell and shock mount though.
