Now for some GOOD news!
It seems that I am recovering from this cold or whatever it is, so now we can return to a relatively normal schedule!
I want to start with some comments from Willie B. regarding string. After you read Willie’s comments, we can talk about the string and why it does what it does: to allow players of any level to play without discomfort.
Here is from Willie:
“FYI, my inability to play tennis more than 1-twice a week due to the pain for over 4 years impacted my game. The last time I was ranked was 5.0, but now at 47, probably more like 4.5 (No tournament for the previous 5 years)
The good news is that with the feel of those strings, I can hit back (I practiced with a top player last Sunday, and he even felt it as I am not scared to go big… I have played with him for over a decade)”.
Willie’s racquet technician is Henry Hamels of String MD. Thank you, Henry, for sharing!
If you have not already guessed, the string material is PEEK, polyetheretherketone, which was marketed as Zyex by Ashaway under the MonoGut ZX and ZX Pro models! This monofilament format offers an alternative to stiffer monofilament strings while providing, in most cases, better performance and durability!
- The raw material is expensive.
- Some
racquet techniciansstringers simply don’t know how to handle PEEK.- The high elongation of PEEK is a surprise to the first-time stringer.
- Marketing hype is not strong.
- Very few players and stringers know about this alternative.
- See Marketing Hype above!
- Stringers may have had a poor experience before and are wary.
- The material does not change shape; therefore, knots are not as tiny as some stringers prefer.
- PEEK will “tighten” its own knots.
- Beginning stringers may over-tighten the knot, causing failure…never to be used again!
- Currently, the material is available in two (2) colors, tan and black.
- MonoGut ZX is 16 gauge
- MonoGut ZX Pro is 17 gauge
Depending on the player’s tennis intentions, we may start them on PEEK at age nine (9) but no later than twelve (12).
Thank you, Willie, for your comments!
To see if this material will benefit your game now and for the long term, ask your racquet technician.

Wilson SHIFT 99 PRO – Jason’s Racquet Review
HIGHLIGHTS:
Fun racquet to try! Very different in both looks and feel, from the usual Wilson offerings. More suited to the advanced player, and aggressive baseliners who play with fast swing speeds, and a lot of spin.
FIRST IMPRESSIONS:
The most noticeable impression, on first pick up, of the PRO version, was the slightly thicker beam, and overall heft of the racquet. At 327g swing weight, this racquet is definitely in the heavyweight category, but it had a good feel in the hand, and generally good maneuverability, both at the baseline and at the net. As for looks, the contemporary aesthetics are very different from the usual Wilson look, and the string bed looks noticeably tighter than I’m used to.
CONTROL:
The sweet spot on this racquet feels small, suiting it to a more advanced player. Faster swing speeds seemed to produce more control, but with the smaller sweet spot, and low dwell time, I experienced some balls flying when I didn’t expect them to. The tight string bed does produce a lower trajectory, but I didn’t find that this prevented those occasional wayward balls. At the net, the racquet had a damper feel than I’m used to, and again, I felt I was in control as long as I hit the sweet spot.
SPIN:
I was looking forward to testing this racquet because of the new increased horizontal bending in the head of the racquet, which should generate more spin. Hitting my regular strokes, I didn’t notice any extra spin being produced naturally. However, when I really tried to increase the swing speed, and increase the spin myself, the racquet responded well and would allow for great spin creation.
POWER:
The thick beam gave the racquet a very solid and stable feel, and with the weight of the racquet, it was very powerful coming off the sweet spot. Great on days you’re playing well, but if you miss the sweet spot the racquet had a dull, non-responsive feel. Solid on returns and good momentum, but the flatter hitter may struggle for control.
OVERALL:
This is a very different racquet that takes a while to get used to. It would be well suited to an advanced player, who swings fast, and already plays with a lot of spin. Don’t expect this racquet to transform flat strokes into heavy topspin. I tested at 55 lbs but would string a little tighter than this if using it again.
I did also test the non-pro version of the Shift. With the more open string bed and lighter weight, I experienced even more balls flying long than with the pro version. It was definitely more forgiving on the arm, and easier to maneuver, but the trade-off was less control. Would be well suited to a more intermediate player. I feel an advanced player would have to add some extra weight, and string tighter.

Wilson Shift 99/300
After the success of the Wilson Labs version of the Shift technology, Wilson decided to make a retail version. We have received the retail version of the unique racquets and certainly want to share!
Just looking at the racquet, you may ask, “What is unique about it?” Even though the term AI is overused, in this case, it was just used! Some of the concepts of the designers were fed to AI, and it went to work!
Wilson Shift 300
We don’t know the details of the AI prompts, but we do know the very wide throat will accommodate the in-plane flexure of the shaft, which lets the head move downward upon impact and then move back while the ball is in contact with the string, therefore, contributing to “spin.”
This 99-square-inch racquet comes in two (2) versions, the 300-gram and 315-gram “Pro,” with an 18×20 string pattern.
We can feel some flex in the shaft; however, the real test is hitting with this concept, so come in and try the demo. In the meantime, take a look at the numbers.
