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!
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!
