you get faster chilling at max flow. I do use the max flow and it works fine. Like I said I use about 15 gallons to chill 5 gallons down to 80*. It's really all about moving the wort past the chiller coils so that the cold wort around the copper moves away and lets hot wort in to cool down. The smaller diameter tube does likely make a big difference though. if you double the surface area of the tube you quadruple the volume inside which means you are pushing 4 times as much water through but only twice as much is making good contact with the heat exchanger
That's along the lines of my thinking. In terms of chilling, it seems to me that you'd be better off with a few more feet of tubing at a smaller diameter than with a larger diameter tube. (To a point anyway. If you get to the point where the water in the tube is practically the same temp as the wort, more length is obviously not going to help much.)
