I'll repeat what Carl said:
"For now we won't be using cross talk in MC and here is why.
In Super Pro, most everyone is using a delay box, and those that don't have the option of running No/E.
Bikes don't have that option and right now few run a box. There are just not enough bikes to split the class. But we do run a blinder, so it is somewhat of a consolation.
I did a random pole and the feedback I got was that the majority of our bike racers want to keep it like it is now."
We don't have crosstalk turned on in MC, so putting an N on your bike will not make a difference.
