Consistency is a component of almost every successful thing we do each day!
But, what does it look like? Well since this is a tennis centric post it will look like this:
What you are looking at is identical racquets, identical string, identical failure location!
If you find the very end of each string you will see how consistent this failure location is.
This string is a high elongation material so will notice that the ends of the broken strings are very far apart.
This is a good thing since it (elongation) contributes to comfort and power when hitting the ball.
This failure location indicates the player is striking the ball with consistency! That many explain the UTR of 13.3!
What else does this failure location show us?
- Most impacts are not in the center of the racquet.
- The string spacing in this area is a little more “open” which may “catch” the ball and contribute to rotation.
- There are more strings for the ball to “roll” over before leaving the racquet which may contribute to rotation.
Consistency is important in everything we do. Visualize it like the string bed of this racquet and try to hit the same spot each time you do something…anything!
If you have been following Racquet Quest online and with the podcast, you know we are very fond of data! In keeping with that “fondness,” we have received our newest testing device, which I have named “Questron.”
During the last week, we have spent time getting Questron set up to do the kinds of testing we think is important for the tennis player, the racquet technician, and anyone else that cares about numbers!
It will be about another week before posting any data because we are “tweaking” some connection points, cycle settings, and refining the data’s graphing.
We have over 400 strings to test; however, we will eliminate many of those strings not relevant to today’s tennis player.
Even in the “testing” phase, we are discovering interesting facts about strings that will help us put together the best setup for you!
This is the “base” Questron. Future versions of this device will incorporate the “Power Potential,” “In-Plane Stiffness,” and “Dynamic Stiffness” testing that is currently done on other equipment.
Does Tecnifibre have the “answer”…again?
We all know Tecnifibre for its terrific multi-filament strings that set the bar for strings of the material and construction. Several years ago Tecnifibre introduced a string that was intended to be arm friendly to counter the increased use of very stiff string.
Since that time Tecnifibre has gotten into the polyester string arena in a big way but they have not forgotten the player that needs a more comfortable string.
Not long ago Tecnifibre introduced Duramix 16 and 17 gauge string. As the name implies there were a couple of fibers used to create a stiffer but still comfortable string. We have used, very successfully, the Duramix 16 and 17. This is a great option for juniors that need some durability without sacrificing their arms.
Now Tecnifibre has introduced Triax! Is Triax the new “answer?”
Triax will replace the Duramix name but deliver the same or better performance and comfort.
Take a look at the String Characteristic Data to see how these new Tecnifibre strings stack up!
The essential function of string in your tennis racquet is to return energy to the ball as it collides with the racquet. It is evident that if there is no string or a broken one, the racquet can not do what it is intended to do, and your shot is going nowhere or worse, everywhere!
There are about thirty (30) string brands, and each brand has about ten (10) different models, and maybe three (3) different colors, so there are nine hundred (900) possible selections! Nine hundred is way too many strings!
You and we need to consolidate string data so we can make the right decision for you, your playing style, and your physical capabilities.
We test every string for elongation, creep, (stability), with a little bit of elasticity data observed. This testing returns our exclusive Power Potential© for each string, and that is the basis of our decision-making process. Naturally, the higher the elongation, the more power the string will return to the ball, and conversely, the lower the power potential, the less power that “can” be generated. You can observe this fundamental by dropping a tennis ball on a concrete floor and then on a strung tennis racquet from the same drop height and see which one bounces the highest.
I use “can” because power, to a great extent, comes from how hard you swing the racquet, which, of course, brings the prospect of overdoing it and subsequent injury! A low power string demands a more powerful swing that involves the entire arm, hips, and legs.
Low power, in the form of a stiff string, has been associated with control, therefore, the increased use of stiff strings. However, with stiffness comes another downside, and that is stability. Stiff strings typically lose tension quickly and need to be changed frequently. So here is the real problem; the string may not be broken, but it is not playing well at all. There is a difference between durability and performance! If your goal is long term performance, a stiff string is not the answer.
What, then, is the answer?
Choose a string with an elongation of 10% or higher! Oh, great! You say. How am I going to know that!
Well, beginning January 1, 2020, I will be posting the power potential of every string we have tested over the years! There are over 500 items on the current list sorted by brand. The color coding is RED if 5% or less, GREEN if 10% or higher, and BLUE for everything else. Note, however, that natural gut is included in this data and will probably not reach the 10% Power Potential© threshold, but is still the best performance string available. This is due to the dynamic properties of the natural fibers, so, until there is a separate classification gut will be included as is.
A previous post, “What is Soft?” goes into graphical detail.
As new strings are added, some older ones may be deleted because they are no longer manufactured. However, some very old ones may remain due to their “legacy” status. This chart is a preliminary format but will get us map toward the right decision!
If you read our recent post about “How to Demo a Racquet,” you may be incentivized to do it!
So while you are at it try one of our performance racquets setup with MonoGut ZX or ZX Pro (thinner) to get the maximum performance from the racquet.
Ashaway MonoGut ZX and ZX Pro have been one of our most popular strings for well over five (5) years!
Top players have been using it, but now the word is spreading that is not just for “the good player” but for everyone! We are very sensitive to injuries and injury prevention, so that is why we recommend MonoGut ZX to almost all players. The durability and feel of this string are unique, and, MonoGut ZX and ZX Pro is a monofilament but is PEEK and no polyester.
As with any string, some will not want to change, but if you are looking for a new racquet, why not demo a racquet setup with MonoGut ZX or ZX Pro?
Ashaway MonoGut ZX and ZX Pro come in Black and Natural and 16 (1.27mm) and 17 (1.24mm) gauge.
