Prince Vortex 300
The new Prince Vortex design is a new offering of an older string pattern with 14 main strings and 21 cross strings in a variable taper beam…whew! You can see by the throat design that the main strings are longer that a conventional throat design. The longer the main strings the more energy they can return…sort of, and in some cases!
Vortex 300
The beam starts at the grip with a strong 25mm then tapers into a 23mm at the throat and then back to 25mm at the tip. Do not let the beam dimensions fool you! The RDC flex of 59 after stringing is quite acceptable for most every player style.
We have been taking coefficient of friction (COF) data for years but have not included it this review format, until now. The 14×21 string pattern is unique enough that it is worth including. You will see the numbers on the review specs so we won’t go into them now, however the numbers are interesting.
The 14 main strings contribute to a very “open” area right about where most extreme “spin” shots are hit according to our data of string failure positions.
The frame geometry is sort of “Aero” like. The shaft is trapezoidal that transitions into a “reverse” trapezoid around the head. It makes the racquet look stiffer than it is!
Take a look at the specs then pick up a demo to see what the numbers mean to you!

Prince RipStick 300
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!

And now for something completely different!
It is not often we get to do something completely different but this is that time!
Everyone loves to see what the very latest racquets are going to look like and how they will play but what about taking a look back, not forward!
This racquet review is going way back! I am not sure when this racquet was made but suffice it to say it was a while ago. I will guess that it is over sixty (60) years old.
Well, OK! What is it?
It is a Wright & Ditson Olympic!
Wright & Ditson Olympic
This is a beautiful 68 square inch wooden racquet. The wooden grip pallet is wrapped with a very wide piece of perforated leather, not the slender leather used today.
The racquet has no butt cap. Or didn’t have a butt cap but now it does.
Pay particular attention to the weight of this racquet, and the stiffness!
Many of the current racquets will be in the 315-gram range with an RDC flex of 55+.
When we received it the condition was not great but it was straight and worth renovating. We all know how beautiful some wooden racquets can be so let’s get to the specifications.

Head Speed Pro Black
As you probably know by now Novak Djokovic plays with a version of the Head Speed but in black, not black and white! So it was only a matter of time until the all-black Speed Pro became available.
Until now we only had the black and white Speed Pro demo but now we have the black one!
This review will include the white and black version of the Speed and we will include a comparison to the Wilson Blade Pro!
