Yonex VCore Series…Red…Hot!

The new Yonex VCore Series is Red and Hot!

 Yonex has incorporated several of their best ideas into this VCore model series.  Some may be easy to overlook but still yeild some performance enhncements, like the “straight hole” design which may allow more string movement and increased dwell time, like the “trench design” that tucks the grommet barrels into a trench to reduce drag, like “areo fin” placement to reduce drag, like “Namd” graphite that flex’s to increase dwell time and spin potential!

Wow!  That is a lot of stuff to consider.  The good thing is that you don’t need to think much about these things!  Instead, go out and hit with one of the four (4) models, 100×280 gram, 100×300 gram, 98×285 gram, and 98×305 gram, and decide for yourself!

All of the racquets look the same so you will need to look for the “100 or 98” on the shaft and then look for the weight on the hoop right above the throat.  There you will find the weight, balance, and length.

Most of the Yonex Performance racquets are made in Japan but this series includes the “Game” model that is made in China but adheres to the Yonex quality standards as far as I can tell.  The “Game” is a lighter version (270 gram) of the same “look” and incorporates most of the design features of the other models.

The data that follows is for the Yonex VCore 100, 300 gram version.  The other versions will follow!
