Wilson Pro Staff Six One 100, v14

Apr 15

Posted by

As you know the Wilson Pro Staff Six One franchise has been around about as long as wooden racquets have been gone!  A long time!

Many racquets have come and gone.  Some should not have “come” and some should not have “gone”, in my opinion.

This racquet, to me, is the epitome of the Pro Staff Six One series for a few reasons.

  • The 100-square-inch head size is ideal.
  • The thin 22mm beam is perfect.
  • The Shiny Rust finish is the best of all Pro Staffs!
  • The geometry and proportions are perfect.
  • The stiffness (flex) is satisfyingly low.

The specifications will tell us more about the racquet, but here are some things that don’t appear on the “spec” sheet.

  •  This is a foam-filled racquet.
  • The FORTY-FIVE layup is used in this racquet.
  • The grommet barrels are large enough to allow string movement.
  • The bumper guard “string valley” is very deep.

Let’s take a look at the specifications.

The initial response to the new Wilson Pro Staff 97 v14 graphics pack is similar to the Blade shifting color graphics…you either like it, or you don’t! There seems to be very little “in-between.”

We like the graphics!

We care about the racquet’s appearance, but we really care about the specifications!  

So here we go…

ZUS Tennis

Never heard of them?  I hadn’t either until yesterday!

ZUS is a Chicago-based company that offers several racquets with various specifications available.

A ZUS Custom Sven Goth Design came in for work, so we had a great opportunity to get all of the specifications and include them in a “racquet review”!

First, the racquet seems to be a well-made version of the Wilson Pro Staff RF, with an ever so slightly thinner modified box section beam.  the geometry is very much like the Wilson Pro Staff RF, as is the weight.

Who wouldn’t want to be modeled after the Pro Staff RF?

This racquet has a bunch of weight at the rear end, plus a shrink sleeve to increase the grip size, so it is loaded up with weight down there, which is OK!

Rear Weight

 

 

The racquet is foamed, probably the entire tube, which may contribute a more muted feel than a non-foamed racquet.  The Pro Staff RF is also foam filled.

The small oval piece is a lead or steel, weight sandwiched between the two halves of the shaft.  This construction makes it impossible to remove that weight if you want to, but it is good to have it there!
