Let’s be Serious about String!
If you know anything about Racquet Quest, you know we are very serious about tennis racquet string!
For years, we have offered strings that may not have had the exposure they deserve. That may be for any number of reasons but the primary reason is most stringers do not want to mess with anything that is different.
We seek out strings that are worthy of our promotion to our clients based on the player’s needs… not ours.
For years Racquet Quest has offered MonoGut ZX and ZX Pro, a monofilament alternative to polyester string. It is our “GoTo” string for several performance reasons, including comfort, stability, durability, and power.
The players that do not need the power of the PEEK material of MonoGut ZX and ZX Pro can now experience the playability and durability of IsoSpeed Professional, Energetic, Speed Control, and Speed Control + Arm.
IsoSpeed uses polypropylene fibers to construct multifilament strings that mimic natural gut in terms of construction and power potential. These extraordinary strings fill a much-needed void in high-performance tennis.
Racquet Quest understands this string material and construction. Our testing confirms the benefit of a durable multifilament string for players who are moving away from a polyester string. You can too!
IsoSpeed started producing tennis strings in 1990. Right after they entered the market, the entire Austrian tennis elite began using ISOSPEED products for competitive sports. The trend toward high-tech products has continued to this day, and ISOSPEED now offers a complete line of strings that is known around the world as unique.
The IsoSpeed line consists of five (5) unique strings, most of which are available in 17 or 16-gauge (1.20mm – 1.30mm)
- Professional
- Control
- Energetic Speed + Control
- Control + Arm Protection
- Professional Speed + Arm Protection
Racquet Quest agrees and is ready to set up your tennis racquet for maximum performance and comfort…“Play Harder…not Hurter™
We will be engaging in serious playtesting. If you are serious about string, let us know!
Weight is Your Friend!
Is this instance we are talking about racquet weight. Not the few pounds we put on yesterday, Thanksgiving Day!
In the early 1990’s we made a tennis racquet which weighed slightly over 7 ounces. Awesome, some said! This racquet traveled along with the standard weight racquets in the line and was available for anyone to hit with.
“Hit” in this case is a misnomer because the mass of the racquet was not enough to get the ball over the net in most cases! Instead of a “hit” it was like a light “shove”!
With out a doubt the weight of a racquet must be “usable”. Take a look at these brief warm-up videos to see weight in action then we will find out how much these racquets weigh and the swing weight…
This is a Wilson Blade 98 18×20 pattern. Racquet weight is 329 grams (11.61 Oz.) with a swing weight of 332 kg/cm^2.
Next let’s take a look at a different player…
This is a Head Radical with the Pro Cap System creating a racquet that weighs 340 grams (11.99 ounces) with a swing weight of 349 kg/cm^2.
It is obvious that both payers are swinging the racquet with gusto and it should be obvious that the racquets are stable on impact and this stability is necessary for power and control.
So the next time your oppponent asks if you have “gained weight” it will because the ball is coming at them with more “heaviness”! And you can repsond “yes!” with a smile on your face! Just like Robert, Sophie, and Aleks!

Need Direction?
A client just sent me the following statement and I think it has reason to be distributed amongst tennis players searching for “direction” when it comes to string and their game!
“Hah. Trying out these different strings has been very interesting. Over the past week or so, trying the different strings has given me some insight into what my game should be. I think usually people do it in reverse. They try to find the string that tailors to their game. By experimenting with the strings, I realize the direction my game should be going.”
“I’ve been coming to realize that my game is better with control and feel rather than power. Experimenting with different strings have helped me recognize this.”
Do you think this applies to you?
