TheLambsheadrep: An initial announcement said Head made 5000 for the US market. Apparently another announcement was that there would be 9000 worldwide. There is a hypothesis that this meant 5k for the USA + 9k for the rest of the world. But no one knows for sure. (http://tt.tennis-warehouse.com/showthread.php?t=108976
). This irked the people who bought this because they thought it would be rare. But its no problem for people like me who really play with the racquet. The more there are floating around the world, the better for me if I need replacements.
It's also been said in another thread that Agassi's Wimbledon championship happened before he endorsed Head. Hence it was not included on the racquet.
