I prefer removable links to fixed switches. We all know what kind of weird damage a robot can get during a fight and in my opinion a fixed switch can be damaged far more easily than a removable link. With the removable link the ultimate tool is a crowbar (ask Derek Foxwell) but what do we do with a snapped switch ?

The other points: frequency, lights, weight of featherweights... that is exactly why the Dutch and other European roboteers abide by the rules established by the FRA. We want as little confusion as possible. But we all know that the USA have more differences in respect to -say- tools and industrial standards than you would think and that there will always be problems. What you need then is an international agreement regarding each others rules when international battles take place. That is the only option.

(The worst example would be like asking USA soldiers to swith to Kalishnikows because all guerilla and terror soldiers use them... stupid no ? Exactly my point.)
