The Wilson Blade 104 has been one of the most popular racquets in the “over 100 square inch head” arena.  It is no wonder since the Williams sisters have been using this model for quite a while.

But now there may be some confusion as to what Blade 104 you want or are getting.  What follows is a brief description of each model and how to spot the one you want.

First, the “header card” on the non-countervail Blade 104 does not have “SW104 Autograph” on it.  Nor does the word “Countervail” or Serena’s autograph show up.

On the inside of the shaft you will see the “Serena” autograph, and on the outside of the shaft, you will see the word “Blade” in gold, not silver as on the non-countervail model. At the inside of the top of the frame you will see”Serena Autograph” inscribed.

It should be obvious, but it isn’t necessarily, is the Serena Autograph model is 28 inches long opposed to 27.5 inches long for the standard model.

So, if you are interested in a new Wilson Blade 104 be sure you are getting the model you want.  Oh, and another way to tell which one you are getting is the Serena Autograph will set you back $249.00 instead of $199.00 for the standard, and 27.5 long model.
