Prince CTS (Constant Taper System) Storm Mid Plus  (I scrolled around the web for spec info on this 1990 racquet, but only found a few user comments / opinion):I currently have the CTS Storm MidPlus as a backup racquet. It is about 12.3 oz strung and only a little head light. Due to the thick beam (26mm at grip/32mm at head) and aerodynamic frame, it is very powerful. I sometime pull it out for doubles use. It is fun to go back to it once in a while. Prince (in RE:  CTS  system)... main characteristic is a thicker tip tapering to a thinner throat. Wilson tends to use a double taper, thinner at the tip and throat, thicker in the middleThere isn't any spec info written on the frame, which is why I scrolled the web for info.  I can't back up the user comments, but I did weigh the racquet and this racquet (as is) weighs 12 3/4 oz, which supports comment #1's weight estimate.There are a few light scuffs on the frame, but I do not see any dings or cracks.  Bumper guard is in good condition, no cracks, etc. Grommets are also in good condition, none missing or broken/cracked that I can see.Grip Size: 4 5/8"Dimensions:  Total Length: 26 7/8" ; Frame width:  10 1/2"The racquet will require a new grip (I put an over-grip on the racquet -  the original grip is worn), and strings.Racquet cover is not available.Thanks for looking!
