some competition aspects:
-ban radio communication
-level chances for ALL national teams at WC - be that, four- or five-man teams, whatever works
I agree with the last one, but I tend to dissagree with the common belief that radios makes boring racing. Radio ban =/= exciting racing. In fact, many of the most exciting races the last couple of seasons have been with radio communication. Without radios the controlling teams do not tend to give the breakaways a very long leash and it ends in a sprint finish anyway. It doesn't make that much of a difference.
As long as the race routes are boring and the amount of riders on a team is too large we will have boring racing. Regardless of having radios or not.
