Have a general question in regards to helmet communcation systems. My wife says I don't always see her signals when it's time to rest or whatever so we are thinking about communication systems for our helmets. I have a flip-up and she wears a full-face. We aren't looking for anything fancy such as blue-tooth or xm radio capability unless there is a good system at a reasonable price. Any information would be most helpful so we could have a system in place for next year's riding season. I know there are alot of different systems out there so we would appreciate any and all help.
