Over the last few years, I have always replaced the original Yonex synthetic grips the very day I bought a new racquet. Why? Simple, using a Yonex over grip, I found when replacing the over grip the old over grip tore the surface of the the synthetic base grip.
Therefore, I would replace the original grip with a Kimony leather tape grip and use the Kimony as my base grip. Using the Kimony accomplished
4 things. One, the racquet grip size was reduced by one grip size. (my 4-1/2 grip became a 4-3/8s) Second, when I put on a Yonex Super Grap over grip and pulled it relatively tight the grip size was 4-7/16. Third when I removed an old over grip the base grip did not tear. Fourth, with the Kimony leather tape base grip the bevels were much sharper.
Works well for me. Of course, I very seldom hit out of the sweet spot, therefore, no hand, wrist, elbow, or shoulder pain.
