I string for my college team, and this is pretty bewildering, as three of our players use the new model of the BLX Six.One 95 18x20. Two of the players approached me with their racquets and complained of butt-caps coming off entirely or feeling loose, and asked if I could fix them. After taking the grip off of one example, all it took was a little wiggle and the butt-cap came off completely. Now granted, these aren't the best images since I took them with my iPhone 4, but the second and third pictures show how many different sections there are in the mold of the handle, while the first picture shows the section that broke off... Along with the staples to hold the butt-cap in place. One of the guys got two of the butt-caps reattached at the ITA All-American tournament, and it appeared that they used some kind of epoxy to reattach the butt-caps to the handle. Both broke off again, so this is a more stubborn problem than I thought it would be. His other two racquets started to exhibit signs of similar defects, and we had to ship three new racquets overnight before his Futures tournament. Now another player has two of his racquets showing the same fate, and one of them is the example pictured. This makes six racquets from two different players with the same defect, with more that worry me of having the same problem. Any ideas as to why this is happening? Two of the guys had the model before this current one without any problems; I can't imagine how much different they could be in handle design. Bad batch? Defective design?? Poor Wilson quality??? Thanks in advance for any thought!
