Soft String…What is it?

In 1994 I did a presentation for the USRSA in Atlanta.  The topic was… “Understanding String”. It is now 2016 and we are still trying to understand string! Especially “soft” polyester based string. In 1994 PolyStar was the only polyester based string I was familiar with. Since then there are dozens of offerings from anyone [see more]

Diadem Strings Added

I just added twelve (12) sets of string provided by Diadem Sports.  Thanks to IART member David Hall for getting this included in the String Characteristic Data, and thank you to Diadem Sports for sending the sets! The common characteristic of the Solstice Power and Elite XT series is the “star” shaped cross section.  The [see more]

Tensile Strength…is it important?

Tensile strength sometimes referred to as UTS is the point at which the string, in this case, breaks during a straight pull.  Tensile strength is not a value a manufacturer will put on the package because it is easily manipulated and can, in some cases, be misleading. For most racquet technicians, tensile strength is not [see more]

Can We Have Both?

Almost since the beginning of the “polyester” era, the “promotable advantage” was the strings ability to slide and snapback creating the much coveted “spin.” However, the packaging of a very popular polyester string makes a contrary claim stating that the string “resists movement”! But, more power and spin! So, we can have both according to [see more]

Yonex String

Yes, Yonex sells string, and has for many years, and still source a lot of them in Japan! I use Yonex TourSuper 850, along with BiPhase, and Remplir, as a premium multi-filament for players demanding playability. With the extraordinary increase in polyester offerings I have included in the String Characteristic Data some Yonex polyester strings. [see more]

Head Velocity MLT

Head has introduced a new string, and, by doing so has joined a group of brands that are still investing in string R&D!  Contrary to some thinking polyester string is not the best string for every player so congratulations to the brands that are contributing. Anyway, the Velocity MLT is a polyamide (nylon) string of [see more]

Babolat M7 String

Babolat recently introduced the new M7 string.  I like the name “M7”! Are you prepared for this?  This string material is polyamide!  Yes!  That is the correct spelling of N-Y-L-O-N!  The word “Nylon” has gotten a bad rap in my opinion but I think it is still the most widely used material for tennis string. [see more]

“Tier One” Strings

I received a full range of strings from Tier One Strings based in San Diego and was anxious to have a look. The packaging is typical of some top brand strings with the perforated side bar that makes it easy to get into.  I find that with this packaging I prefer to slice it open [see more]

YTex Strings

Recently I received ten (10) sets of YTex string which, I believe, represent the latest offerings from this company.  You can see the “Power Potential” data later but first there is one thing that sets some of this string series apart. That one thing is “polyolefin”, which is, simply, a soft thermoplastic material that can be [see more]

Tecnifibre Strings Added

Five (5) new strings from Tecnifibre have been added to the String Characteristic Data.  Typical of Tecnifibre strings most of these are multi-filament with polyurethane (not polyester) binders.  The Razor Code is a polyester based string and the power potential indicates that. The ATP World Tour 17 came in a discrete plain brown wrapper so [see more]
