Just switched to the blx 98 and am confused by a few issues between the two racquets I received. One of the racquets doesn't have the text on the butt, like the grip size and other wilson coding I assume. The same frame's red centering dot on the hoop is bigger than on the other. The same frame has no string rec text in the throat, the other does. And though they both have the pro hybrid grip, this same frame has a contoured, or riveted version. New to wilson, and needless to say, I have no idea what to make of all these differences. Thoughts?
