I started using the HEAD Pro Tour around 1996. I got all my racquets straight from HEAD Austria. They all had the "Made In Austria" insignia on them. I don't know the exact number, but I must have gotten through a ton of those racquets. They all felt identical in every which way. Except one! Every time I used it I just wanted to smash it after 20 minutes, and after about 40 minutes of play I always lost every bit of feel for the ball, especially on the backhand side. Like I never hit a backhand before in my life! And it's my best shot.... Anyhow. The racquet always escaped execution, and I kept it as a back up racquet, just in case I ran out of all other strung racquets, so it kept infuriating me for years. In 2001, after a practice session, a friend of mine borrowed it, and as he looked at it for about 5 seconds, he told me; "...did you know this racquet is DESIGED IN AUSTRIA, as opposed to Made in Austria...?" I grabbed the racquet and and to my horror I see it. What the f@%&!!!! Finally it got what it deserved on the net pole at Indian Wells.
I don't know how that got through the cracks and what it was doing amongst all the others in Kennelbach.
That's my experience with the "Designed in Austria" Pro Tours. They are farmed out rackets, and basically authorized fakes. Otherwise, I can't explain how they made it back to the factory in Austria.
