So, what IS the difference?
Wilson has presented us with a couple of choices when it comes to choosing a 100-square-inch racquet!
Later we will have a comparison table showing the pertinent property data, but now we can see the graphics difference between the two racquets:
The Pro Staff Six-One 100 has a very shiny rust color. The Pro Staff X is the matt finish used on most of the v14 Pro Staff models.
In addition to the “shining,” the Six-One has the “normal” elliptical cross-section, while the “X” has a “box beam” geometry which is a little more narrow.
The string spacing on the “X” is slightly more open, which may contribute to the power calculation being a bit higher.
The flex of the “X” is a little greater in the shaft area.
That is enough talk!”
