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.”

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.
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!
