When you are on tour in the UK it takes a few hours to get anywhere. A lot of the time you can have a beer, close your eyes for two minutes, and then you are there. In the U.S. it is much more like a road trip as all the cities are so spread apart.
I do like the idea of pulling in different producers to get new perspectives. That's what I did with Vows and I feel it just gives variety and makes for a more exciting journey for the listener.
