I got 6.24, but its on the border of being dark... .
It Uses a little too much welding + tension that might produce some dark force. Eh. Its up to Dr Roy though. The welding force that pushes a node out of material isnt really noticable, compared to the ton of tensioned rubber behind it.
I would rather win Dark. I really do have 5.26 Super Dark. hehe.
Edit: No tweaking 0.02 off your score just to beat me now! contest is over! lol
