And Now This…

In the words of Lord Kelvin (May 1883) “When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in [see more]

String Failure (continued)

In a previous post, we saw string failure(s) for the same string, i.e., not a “hybrid” format. In this post, we will see the typical failure of a “hybrid” format using polyester for the main string and a multifilament for the cross string. The polyester string shows very little wear whereas the multifilament cross string has [see more]

Know Your History!

As racquet technicians, we are bombarded with “new product” information! Especially when it comes to racquet string! So what do you and we need to know when making a string decision? History, that’s what.  The image shows just some historical data points. We can look at data for any string and client to determine the history [see more]

String Failure Redux

What if the strings break before you can re-string, and why do they break! Strings wear out!  The picture shows what that may look like.  A clean break close to the area the ball is hit most often you will see “notches” caused by the rubbing friction between the strings.   This is an OK [see more]

Yonex VCore Pro 97 – 330

Finally, we get to the VCore Pro 97 -330 which you can probably guess is the “playerest” of the new Yonex VCore Pro Series. This is one of those racquets you can just pick up and play!  No need to fuss around with weight, swing weight, and other stuff.  Just play. As noted before every [see more]

Yonex VCore Pro 97 – 310

Yonex continues their tiered performance racquet concept with the VCore Pro Series.  In this case, there is the VCore Pro 97 – 330, the VCore Pro 97 – 310, and the VCore Pro 100 – 300.  For racquets that look the same they each feel substantially different in a right way, I think! This review is [see more]

Yonex VCore Pro 100 – 300

Yonex updates their performance series with the introduction of the VCore Pro Series.  This series consists, right now anyway, of three (3) racquets;   Pro 97 – 330, Pro 97 -310, and the Pro 100 -300.  These are the thin beam, slim geometry style which has been the hallmark of the Duel G Series. All of [see more]

What Does Your String Logo Mean?

Some players like to have a “logo” on their strings while sponsored players must have a “logo” on their strings.  Pro Players typically have the racquet brand, and the string brand (if different than the racquet brand) proudly displayed. But what if you are not getting paid to play with a particular racquet or string brand? [see more]

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 [see more]

String Shape Considerations

Monofilament string can be easily produced in almost any shape.  Round, square, triangular, hexagonal, octagonal etc.  So, on the surface that seems like a good thing.  Who wouldn’t want the sharp edges digging into the ball creating even more spin! But, there may be a side to the shape that needs considering and that is tension as [see more]
