What is “Soft”?
For many years, we have been testing string for elongation and subsequent power potential.
There is a new batch of strings that include the term “soft” in the promotional language, seemingly in an effort to mitigate the injuries associated with very stiff strings.
At some point, we can go into detail about how the soft version of a string compares to the non-soft version; however, for now, I want to reintroduce you to a post we did in 2016… almost ten (10) years ago!

Thank you for reading this again. It is important “Play Harder not Hurter™”
Why String Bed Stiffness (SBS) matters.
String bed stiffness is a critical performance metric and therefore deserves more attention than it gets in the discussion(s) of string characteristics.
In this video, which is a little “jumpy” at first, you will see the data we collect for every racquet we do. For this discussion, we concentrate on these data:
- Reference Tension
- RDC string bed stiffness
- Flex Four-string bed stiffness
- Racquet Quest SBS (String Sense) stiffness
- Effective stiffness
- Master Tensometer string bed stiffness (kg/cm^)
Use Your String
We want you to play your best, and using your string is a component of your performance.
If you have any questions about your string and the best stringing technique, please let us know. We can provide information that may help the tournament stringing team meet your expectations.
Big 10 Tennis Player of the Week.
Jack Anthrop has been playing extraordinary tennis for a long time and was recently named Big 10 Tennis Player of the Week after an impressive outing in Dallas!
The link below will take you to the Ohio State post; however, I want to share some of the things Jack has done to secure the game he has.
Jack uses a Head Speed SMU racquet. The head size is 96 square inches and has a swing weight of 333 kg/cm^. This inertia couples with the overall weight of 352 grams (12.4 oz) to create stability and power.
Jack uses MonoGut ZX Pro natural at a reference tension of 56 pounds and string bed stiffness of 60 pounds. This creates a dynamic stiffness of 393.6 PPI.
Jack has been using Ashaway MonoGut ZX Pro since the age of 9! Yep, that’s right, age 9! MonoGut ZX and ZX Pro material is PEEK, a unique string that offers outstanding comfort, feel, and power with better durability than some other materials.
It is our position that more players of any level should consider MonoGut ZX or ZX Pro (thinner). It really just makes sense…just ask Jack, Big 10 Men’s Tennis Player of the Week!
Let us know if you have questions about Jack’s racquet or string. We have been working with Jack since age 9, and we would like to share what we can to help achieve your tennis goal(s).
Thank you, Head and Ashaway, for your continued support!
