The first one i received was direct from Head via warranty replacement. I assume it was a fresh batch since I had to wait awhile as they were back ordered. I picked up a 2nd one last week because I needed a pair for regionals. As anal as it may be, I brought my scale and of the 4 that were in the store, I grabbed the one that was closest matching as possible. They had been in the store since January when it was first released. Couple things I noticed, the older one in the store just had a picture of wawrinka and simone, the grip size, despite being 4 3/8, felt like a 4 1/2. All the the 3/8's felt bigger in the store actually. The one Head sent me had a picture of Haas on it, and the grip felt like the 3/8's i'm used to. I strung both of my racquets at the same time, with the same tension. However, this one from the store feels WAAAAAAAAAAAAY softer on impact than the other, and this is was the first weekend it had been hit with compared to my other one I've been using for over a month. Scratching my head at this one.
