This is a high-performance string that has gone unnoticed for a while and I don’t know why!
Pro Stock Limited Reserve is a string we purchased because it has interesting characteristics that appealed to us however the client base is small. Recently, however, with the number of players that are moving away from a polyester string, this has become a popular alternative!
In a word, this plot looks very much like that of natural gut, and whatever you think natural gut is still considered the best performance material for racquet string!
What are we seeing here:
- Linearity, the more linear the string the more consistent (predictable)
- Elongation, at 33.1 mm at 50 pounds
- Elasticity, 71.9 %
- This is the area where the advantages of pre-stretching will be seen.
- The curve will become essentially one line meaning the string returns to a nominal length after stretching.
- Ultimate Tensile Strength, 163.6 pounds to fail (high), @107.2 mm deflection
- Knot strength, @102.4 pounds, and surpasses natural gut in this property.
What we can’t see in the plot is the construction of this multifilament string. Each strand is a thin, flat ribbon of polyolefin material. The ribbons are much like the natural gut.
The plot below is a comparison of natural gut string and is included as a visual to compare to Pro Stock Limited Reserve and show how much natural gut fibers are the same for any string manufacturer. Of course, manufacturing techniques, bonding agents, and coatings make the difference between a good gut and a not-so-good gut!
If you compare the Pro Stock Limited Reserve to natural gut you can quickly see why it may be a good string to try!
As you know, Racquet Quest is a data-driven business, and data requires numbers. To generate those numbers, we have designed and built several devices.
One device is the Questron!
The Questron is used to test every string we receive, and the data is compiled to understand where that particular string fits.
So, instead of talking about it we have included a short video!
Thank you for watching our Questron in Action! If you have a question, or a particular string of interest, please let us know. We may have already taken the data! On GASP.network there are many graphs of previous tests. GASP.network is a membership ($40.00 one time) site.
The big BOOM you heard was the arrival of the new Head Boom MP and Boom Pro racquets at the World Headquarters!
This is very exciting news for those that have been waiting!
The wait is over!
For those that pre-ordered, your racquet will be prepared for you quickly. For those that have not yet tried the new Boom series…what are you waiting for?
We also offer Full Custom Boom MP and Boom Pro racquets that are built for you including longer length if desired.
Either way, we think you will be hearing more big Booms very soon!

These are limited in quantity and require complete customization and assembly to create a full custom racquet for you.

We have designed an “order” format however it does not allow for the conversation necessary to create your racquet, so…
Use the “Easy Order” tab to get started.
We have a few “full custom” racquets remaining and when these are gone there will not be any more until later in 2022!
So, if you are interested in a “special” racquet for yourself or a tennis player you like, now is the time!
We have Head Extreme Tour, Head Extreme MP, Gravity Pro, and Head Speed MP in very limited numbers. These racquets can be configured in lengths up to 27.75 inches, in any grip size from 1/4 to 5/8 ( 2 to 5), and any weight and swing weight. Either leather or synthetic grips are available.
Of course, custom stringing can be added. All orders must be received by December 13th if you need your full custom racquet for a gift.
Please use the Easy Order tab on this site if you have any questions or want to place your order. You may text us at 407.491.4755
