Hi. I have 3 of Wilson Blade BLX 98 18x20. But one of them (the left one in gold, forth from the left) is a bit extended, and the end of the grommet is longer than other old Blades. You can see in the photo that the paint on the left gold BLX one also doesn’t align with other 2 BLX. The beam on the throat (when look from the front view) is also slightly thinner. Do you guys know what it is?
