Prince RipStick 300

Aug 7

Posted by

I am not saying the is not a serious tennis racquet but the first descriptor that come to mind is “fun”! And who does not want to have a little fun while playing tennis, huh?

RipStick 300


This is one of the remaining racquets with the “O” Port technology which is very large string openings instead of small grommet holes. The design allows for much more string movement and the 16×18 string bed helps!  The “O” Ports create an effective head size of 105 in a racquet that measures 100 square inches.

But, just look at those colors!  I think they are awesome!

This is a constant taper beam starting at 22.5mm going up to 27mm so if you are “thin beam” person you may hesitate to hit with this racquet, but we think you may be missing out!

If you just look at the racquet you may think it to be quite stiff.  That is not the case!  With an RDC stiffness of 62 after stringing we arrive at an effective stiffness of 30.2 with this string setup.  Not bad!

Take a look at the specs then come get the demo and see what all these numbers mean to you!

Prince Phantom 107G!

Aug 1

Posted by

Prince!  What can you say about the brand that “normalized” over sized racquets!

So, instead of talking about “what was” we will talk about “what is!”  And “what is” is exciting, I think!  With so many really good tennis racquets to choose from why would you choose a Prince racquet?  With this review we will explore the reasons you may want to consider it!

THE PRINCE PHANTOM 107G

Prince Phantom 107G

If this racquet had a high gloss finish and some green lines instead of the current matt finish you could not tell it from the original Prince Graphite.  In other, words it looks terrific.

The beam tapers slightly from about 17.5mm at the top of the grip up to about 21mm at the tip, but by just looking you would say it is a straight  beam design.  The proportions of the racquet are “classic” and the “torsion bar” in the throat contributes to that classic look.

And speaking of classic, the grip shape and the “torsion resistance system” at the 10 and 2 o’clock positions are classics!

So, take a look at the other specs of this racquet and if you like what you see come by at take it for a “demo”

Bolt 100 v2

Mar 15

Posted by

Bolt tennis racquets have been around for a few years and we have reported on them in the past, however, the new V2 of the Bolt racquet lineup is very impressive!

If you are not at all familiar with the Bolt technology it is the “Zip Strip” that makes them unique.  The “Zip Strip” is a carbon fiber component that looks like a miniature tennis racquet cross-section that fits into the sides and top that actually do the “bending” during string and racquet impact!

This “bending” can mitigate harshness associated with very stiff strings or a very stiff racquet!

Arm problems are no match for the ZipStrips!

Before we look at the specifications you can visit the Bolt site for more information.

Head Graphene 360+ Radical S v21

Jan 25

Posted by

From our perspective the Radical S should be one of the most used of the Radical Series!

Head Graphene 360+ Radical S

Why?  The 102 square inch head size is optimum for players looking for additional power,( and who isn’t) in a legitimate players racquet.  We say “legitimate” because this racquet can be turned into any thing you want, now or in the future!

As you will see in the specifications this is not a really stiff racquet so it will be easy for many players to customize the string bed to suit current playing style with an eye toward becoming a more aggressive player, or not!

The Radical S continues with the “control pattern” and “sound grommets”.  We are not totally certain what the “sound grommets” do but sound is frequency and frequency can be felt so maybe the grommets are damping out some of the higher frequencies?

Anyway, this Radical S model is a great step into the “performance” racquet arena with plenty of room to grow!
