Davis Cup has become predictable over the last few years with the home team gaining a significant advantage due to surface choice. For instance, the semi final between Spain and USA almost seems a guaranteed lock for the Spanish. To make the event more interesting, I think the latter stages of Davis Cup should be played using a home and away format system. This would be like a 'two legged affair', similar to football matches in europe. Granted, this would impinge on the current ATP Schedule but more importantly, it would provide a better representation of the best 'tennis nation' in the world. Any opinions?
