Ive been following this thread with great interest and i have come to a few conclusions (Please feel free to correct me). The LED idea sounds great and should be a requirement. I think the point that Roger is trying to make is that the LED may make some roboteers rely on it more than an actual visual check of the link. Babeth i think that every event should have someone like you, to yell and ensure that everything is done safely even in the heat of the moment.

if it is damaged by accident then the fight is paused while it is inspected or fixed.

How would a safe inspection be carried out in the middle of a fight if the link appears to have been damaged?
